A crate slides along the floor for
before stopping. If it was initially moving with a velocity of
, what is the force of friction?
A cat bats at a toy mouse. The mouse starts at rest and, after being struck, has a velocity of
. The cat's paw is in contact with the mouse for
. How much force did the cat exert on the mouse?
A hammer moving with a velocity of
strikes a nail, after which the hammer has a velocity of
. If the hammer strikes the nail with
of force, how long were the two in contact?
A object moving at
strikes a
object at rest. After the collision, the first object is motionless. What is the velocity of the second object?
A crate slides along a floor with a starting velocity of
. If the force due to friction is
, how long will it take for the box to come to rest?
Susan pushes a car with
of force along a frictionless surface. How long does she need to push the car to get it to a velocity of
, if it starts at rest?
A hammer moving with a velocity of
strikes a nail. The two are in contact for
, after which the hammer has a velocity of
. What is the force of the hammer on the nail?
A ball hits a brick wall with a velocity of
and bounces back at the same speed. If the ball is in contact with the wall for
, what is the value of the force exerted by the wall on the ball?
A tennis ball strikes a racket, moving at
. After striking the racket, it bounces back at a speed of
. If the ball is in contact with the racket for
, how much force did the racket exert on the ball?
A ball hits a brick wall with a velocity of
