If the speed is constant the frictional force must be equal to the propelling force (which is gravity in this case) as any imbalance of forces creates an acceleration.
If the 60N is in the same direction as the movement, then the frictional force is also 60N. If 60N is the gravitational force, you'll have to use the angle to calculate the propelling force that acts in the direction of movement. Again, the frictional force will be exactly the same as the propelling force in the direction of movement (only in magnitude, though - the direction of the frictional force (the vector) will be in the opposite direction).
What else can I help you with?
If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
If air resistance is neglected, the motion of an object projected at an angle consists of a uniform downward acceleration due to gravity combined with constant horizontal motion at a constant velocity. The vertical component of the velocity changes uniformly due to gravity, while the horizontal component remains constant throughout the motion.
How do the horizontal components of a projectile motion vary from the vertical components?
In projectile motion, the horizontal component of motion is constant and does not change, while the vertical component is affected by gravity causing it to accelerate downwards. This results in a parabolic path of the projectile where the horizontal distance traveled is determined by the initial velocity and angle of projection, while the vertical distance is influenced by gravity.
Which of the velocity component of projectile changes and other remain constant why?
The vertical velocity component changes due to the effect of gravity, which causes acceleration in the downward direction. The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming air resistance is negligible).
Infer the motion of a car whose speed-time graph shows a horizontal line followed by a straight line that slopes downward to the bottom of the graph?
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.
What causes a ball to follow a curved path when you throw it?
When you throwa balland give it aforwardmotion, Gravity pulls the ball towards thecenter of earth. The ball has two motions ... horizontal (forward) and a downwardmotion. The horizontal speed is constant, or at least nearly constant, but thedownward speed is constantly growing because of the downward gravitational forceon the ball. A constant horizontal speed together with vertical acceleration is a surerecipe for a curved path.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
You can hold a heavy box against a rough wall and prevent it from slipping down by pressing only horizontaly How can the application of a horizontal force keep an object from moving verticaly?
Applying a horizontal force creates friction between the box and the wall, which opposes the vertical force of gravity pulling the box downward. The greater the horizontal force applied, the greater the frictional force, preventing the box from slipping vertically.
What is the downward acceleration of a thrown object in projectile motion?
The downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
What type of motion describes the horizontal component of a projectile?
The horizontal component of a projectile follows uniform motion, meaning it moves at a constant velocity in the absence of air resistance or other forces. This motion is independent of the vertical motion of the projectile.
What are the horizontal and vertical components of the acceleration vector at the maximum height?
Neglecting air resistance, the components of acceleration of an object that's dropped, tossed, pitched, flung, lobbed, heaved, launched, or shot are constant. The horizontal component is zero. The vertical component is 9.8 meters per second2, directed downward. These are both constant throughout the object's trajectory.
What does a strong negative correlation coefficient mean?
The graph follows a very strong downward trend. Would have helped if you specified which correlation coefficient; there are different types.
Derive an expression for acceleration of a body moving downward on an inclined plane making angle 0 with the horizontal when friction is present?
The acceleration of a body moving downward on an inclined plane with angle θ when friction is present can be expressed as: a = g(sinθ - μcosθ) where: a = acceleration of the body g = acceleration due to gravity θ = angle of the inclined plane μ = coefficient of friction
