If the same net force is applied to a yo-yo with a mass of 0.5 kg how will the rate of acceleration be affected?
It has no net force.
A 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell How large is the NET vertical force acting on the barbell?
If a 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell, the NET vertical force acting on the barbell is 1000 N. It does not matter how heavy the weightlifter or the barbell might be.
If an object with a net force move?
I'm not entirely sure what the question is asking. I'll take a stab at it though. An object that has a non-zero net force applied to it will move. It will accelerate in the direction of the net force at a rate given by F / m, where F is the net force (N) and m is the mass of the object (kg).
Sample problem of force and motion?
Detrmine the acceleration of a car of mass 900 kg when a net force of 2700 n acts on it
Starting from rest a 2 kg body acquires a speed of 8ms in 2 seconds the net force acting on the body is?
Starting from rest, a 2 kg body acquires a speed of 8 m/s in 2 seconds. The net force acting on the body is
A car whose mass is 2000 kg is accelerated uniformly from rest to speed at 15ms in 10 seconds The net force accelerating the car is?
3000 N
What is the net force acting on a 015 kg hockey puck accelerating at a rate of 12 ms2?
Newton's 2nd law of motion: F = M AForce = (0.015 kg) x (12 m/s2) = 0.18 kg-m/s2 = 0.18 newton
What is the net force on a backpack with a mass of 12.0 kg and an acceleration of 0.5 m s2?
Net force is 6N
What is the net external force of an object?
How do you determine the net force on an object? Decide which direction is positive motion. Motion is the opposite direction is negative The forces must in a straight line!! Add all the forces in straight line acting on the object. Example To the right is positive A 5 N force pushes a 10 Kg object to the right. A 2 N force pushes the same 10 Kg object to the left. The 5 N forces is positive and the 2N force is negative Net force = +5 N - 2 N = + 3 N To determine the acceleration use Newton's 2nd law of motion F = Mass * acceleration + 3 N = 10 Kg * a a = 10 Kg ÷ + 3 N a = +3 ⅓ m/s^2 The positive sign means the object is accelerating to the right!! If the forces are not linear, you must use vectors, but the net force in any direction is still the sum of the vectors in that direction.
If the same net force is applied to a yo-yo with a mass of 0.5 kg how will the rate of acceleration be affected?
It has no net force.
With what force will a car hit a tree if the car has a mass of 3000 kg and it is accelerating at a rate of 2 ms?
Force = (mass in kg)x(acceleration in m.s^-2)
A 3 kg cart on a level surface slows down at 15 meters per second squared What is the frictional force accelerating the cart?
The cart is decelerating, not accelerating.
What is the net source acting on a kg hockey puck accelerating at a rate of MS?
Numbers are important.F = ma. So multiply the acceleration in meters per second (per second, which you appear to have left out) by the mass in kilograms and that will give you the force in newtons.
How much force is needed to accelerate a 3 kg skateboard at 5m per s squared?
Force = mass * acceleration Force = (3 kg)(5 m/s2) = 15 Newtons ===============( takes about 1 Newton to press a doorbell )
A 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell How large is the NET vertical force acting on the barbell?
If a 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell, the NET vertical force acting on the barbell is 1000 N. It does not matter how heavy the weightlifter or the barbell might be.
A Diwali rocket is ejecting 20 gm of gases per second at a speed of 200mswhat is accelerating force on the rocket?
A Diwali rocketis ejecting 0.05 Kg of gases per second at a speed of 400m/s. What is the accelerating force on the rocket.
How much force is required in Newtons to accelerate a 4 kg skateboard along with its 46kg rider at 3 ms2?
Force = mass * acceleration Force = (4kg + 46kg) * 3 m/s2 Force = 50kg * 3 m/s2 Force = 150 kg*m/s2 or Force = 150 Newtons
