How much force is needed to bring a 3200 lb car from rest to a velocity of 44ftsec in 8 sec?
How much force is needed to bring a 3200 lb car from rest to a velocity of 44ftsec in 8 sec?
a = (vf - Vi)/time
a = (0 - 44)/ 8
a = -5.5 m/s^2
F = m * a
Since the weight is given in pounds, gravity = 32.2 m/s^2
W = m*g
3200 = m * 32.2
m = 99.4 Slugs
At least that is what we used to call mass in the English system
F =99.4 * -5.5
F = -546.7 lbs.

Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
What force is needed to slide a mass of 54 kg at a constant velocity along a surface on which the coeffcient of friction is 0.43?
The force needed to slide the mass at a constant velocity is equal in magnitude and opposite in direction to the frictional force. The frictional force is calculated as the coefficient of friction multiplied by the normal force (frictional force = coefficient of friction * normal force). Hence, the force needed would be 0.43 times the weight of the mass (force = coefficient of friction * mass * gravity).
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
How do you calculate distance when given velocity and weight?
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.
What is the product of force and velocity?
Impulse
A car goes forward along a level road at constant velocity The additional force needed to bring the car into equilibrium is?
The additional force needed to bring the car into equilibrium would be equal in magnitude and opposite in direction to the force that was providing the constant velocity. This force is the force of friction that acts to oppose the motion of the car.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
What type of force is needed to change the velocity of object?
force of compression
What is the relationship between the mass and the velocity of a whirling object?
The mass and velocity of a whirling object are directly related. As the mass of the object increases, more force is needed to maintain the velocity, leading to an increase in velocity. Conversely, decreasing the mass decreases the force needed and therefore the velocity decreases.
Is the force needed to accelerate a car greater than the force needed to accelerate a bicycle to the same velocity?
Force is directly proportional to mass. Therefore, even both the car and bicycle are being accelerated to the same velocity, accelerating a car would require more force since it has a greater mass.
What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
Is a force needed to keep a moving spacecraft moving in a straight line?
It depends where the space craft is. If it is in deep space far away from any large mass (like a planet, star, etc) then the answer is no. If it is close to a mass then the answer is yes. An equal and opposite force is required to balance the gravitational force to keep it moving in a straight line.
What force is needed to slide a 250-kg crate across the floor at constant velocity if the coefficient of sliding friction between a crate and a horizontal floor is 0.25?
The force needed to slide the crate at constant velocity is equal in magnitude but opposite in direction to the force of friction. The force of friction can be calculated as the product of the coefficient of friction and the normal force acting on the crate (weight of the crate). Therefore, the force needed would be 250 kg * 9.8 m/s^2 * 0.25 = 612.5 N.
What is the relationship between radial force and angular velocity squared?
The relationship between radial force and angular velocity squared is described by the centripetal force equation, which states that the radial force required to keep an object moving in a circular path is equal to the mass of the object times the square of its angular velocity, multiplied by the radius of the circular path. This relationship shows that an increase in angular velocity will result in a corresponding increase in the radial force needed to maintain the object's circular motion.
Why when the mass increases velocity decrease?
When mass increases, more force is needed to accelerate the object to the same speed due to its increased inertia. This increase in force required causes the velocity to decrease because there is a limit to how much force can be applied. Essentially, the greater mass resists changes in motion, resulting in a decrease in velocity.
Before the 17th century what ideas did people have concerning motion velocity and acceleration?
There were many different ideas, but they all went something like this: Most people thought that the natural state of an object was at rest, and that force needed to be applied in order to keep an object moving at constant velocity. Of course, we now know that no force is needed for constant velocity, only acceleration.
What force is needed to slide a mass of 54 kg at a constant velocity along a surface on which the coeffcient of friction is 0.43?
The force needed to slide the mass at a constant velocity is equal in magnitude and opposite in direction to the frictional force. The frictional force is calculated as the coefficient of friction multiplied by the normal force (frictional force = coefficient of friction * normal force). Hence, the force needed would be 0.43 times the weight of the mass (force = coefficient of friction * mass * gravity).
