An asteroid with a mass of 5.0 x 105 kg collides with the Earth and slides horizontally along the ground without bouncing (not actually possible but just pretend). The velocity of the asteroid before...

Which is larger, the normal force or the force of friction?

To determine the coefficient of friction between a rough surface and a block, the surface is kept inclined at 45° and the block is released from rest. The block takes a time t in moving a distance...

this is a question of friction i want the answer

Bob is driving his 2400 kg car on a wet road at 50 mph when he sees a tree branch in the middle of the road 60 meters ahead of him and immediately slams on the breaks. If the coefficient of friction...

what will happen to the coefficient of friction between the sofa and the door room floor if the students roomate sits on the sofa while he tries to slide it

Duane has a mass of 73 kg and slides down an icy hill on a sled. The hill has an angle of 15 degrees and there is no friction. I know that acceleration is the change in velocity/...

Science question: If the car is started on a zero friction surface and zero air resistance but force of gravity acting upon it, Will it continue to travel at a constant speed even when engine is switched...

I would like help with the question I just asked

Because of friction pendulum clocks need a small driving force, if accidentally it was too large of a driving force and caused a bit too large of an angle of oscillation to be formed what would happen...

A 100N Box (initially at rest) is pushed 10.0m, up a rough ramp by a horizontal applied force of 150N. The ramp is inclined at an angle of 30 degreees and the coefficient of kinetic friction between...
