A soccer ball is released from rest at the top of a grassy incline. After 8.6 seconds, the ball travels 77 meters and 1.0 s after this, the ball reaches the bottom of the incline. a) What was the magnitude of the ball's acceleration, (assume it to be constant)? b) How long was the incline? c) What angel does the incline make with the horizontal?
The length of the A 2 kg block is released from rest at the top of a rough 40° inclined plane incline is 10 m. As the block slides down the incline, its acceleration is 3.0 m/s incline 1s 10 m. incline. Draw the free body diagram. a) Determine the magnitude of the force of friction acting on the bloc b) W hat is the speed of the block when it reaches the bottom of the inclined plane?
A small block is released from rest at the top of a frictionless incline. The distance from the top of the incline to the bottom, measured along the incline, is 3.80 m. The vertical distance from the top of the incline to the bottom is 1.20 m. If g = 9.80 m/s2, what is the acceleration of the block as it slides down the incline?
A bowling ball is placed at the top of an incline and released so that it rolls, without slipping, down the hill. Which of the following are true? (Select all that apply.) The bowling ball's velocity is changing, therefore its acceleration is changing. The bowling ball is getting faster as it rolls downhill. The bowling ball is experiencing an increase in its total energy as it rolls down the hill. The bowling ball is experiencing linear acceleration. The bowling...
A 6-kg ball is released from rest and rolls down an incline.
When it reaches the end of the incline it falls through a height of
3 meters to reach a waiting cart.
How far from the base of the table should the waiting cart be
placed?
Essentially, how far away will the ball land from the base of
the table?

A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 3.0 times 10^-3 s. The force exerted on the ball by the foot is given by F(f) = [(6.0x10^6)/-(2.0x10^9)t^2]N for - lessthanorequalto t lessthanorequalto 3.0x10^-3s. Find the magnitude of the impulse delivered to the ball. Find the magnitude of the average force exerted on the ball by the player's foot. Find the magnitude of...
A pool ball is released from rest at the top of a 1m high ramp. The ramp makes an angle of 34 degrees with the horizontal. The pool ball rolls to the bottom of the ramp and then smoothly continues to roll up the adjacent ramp that is .5m high and makes an angle of 12 degrees with the horizontal. Calculate the velocity of the pool ball as it reaches the very end of the 12 degree ramp.
and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 51° from the edge of the building with an initial velocity of 17 m/s and lands 67 meters away from the wall. How tall, in meters, is the building that the child is standing on? A boy uses a slingshot to launch a pebble straight up into the air. The pebble reaches a height of 37.0 m...
A 3.00-kg block starts from rest at the top of a 30.0 degrees incline and slides a distance of 2.10m down the incline in 1.80 seconds. a) Find the magnitude of the acceleration of the block. (_______ m/s2) b) Find the coefficient of kinetic friction between block and plane. c) Find the friction force acting on the block. Magnitude ____________N Direction: ______________ d) Find the speed of the block after it has slid 2.10m. (___________m/s)
A block is released from rest at the top of an inclined 6.20 m
long. The angle of the incline with respect to the horizontal
direction is and the coefficient of kinetic friction between the
block and the surfaces (incline and horizontal) is . The block
slides along the incline with constant velocity and continues
moving along the horizontal surface until it comes to rest. Using
the work-energy theorem, Determine:
a) The speed reached by the block at the bottom...
