Question

a ball starting from rest at the top of an inclined plane accelerates at 2m/s2 and reaches the bottom of the plane in 2 seconds. What is the length of the plane?

Answer #1

a. A 0.200kg ball starting from rest rolls down an inclined
plane with θ=30°. Find the acceleration of the ball and the
magnitude of the normal force exerted by the plane.
b. For the ball from part a, if it starts from rest
at a height h = 30.0 cm above its position at the bottom of the
incline (measured between the center of the ball at each position),
what is the speed of the ball vf at that bottom point,...

A sphere is released from rest at the top of an inclined plane.
What is the speed of the sphere at a distance 6.0 m below its
starting point. Assume that the sphere rolls without slipping.

A block slides down an inclined plane, starting from rest and
being pushed with a constant acceleration of 5.25 m/s2 over a
distance of 18.0 cm. It then decelerates at a constant rate of 1.10
m/s2 (because of friction), until it again comes to rest. Find the
total time the block is in motion.

Starting from rest, a car first accelerates at a rate of (2.00 +
A/10) m/s2 for (1.20 + B) seconds and then continues at
the resulting speed for (24.0 + C) seconds. Determine the total
displacement in meters of the car during this time. Round your
answer to three significant figures.
A = 8
B = 1
C = 12

A 1 kg block, starting from rest, slides down a 22 degree
inclined plane that is .55m tall. At the bottom, the 1 kg block
collides with a 3 kg block. The two blocks stick together and slide
.52 m on a friction less horizontal surface for .52 sec. What is
the speed of the 1kg block before it collides with the 3 kg block?
What is the acceleration of the 1kg block as it travels down the
inclined plane?...

A box sits at the top of an inclined plane with a height of 6
meters. The plane is tilted at an angle which is just barelysteep
enough to make the box to begin sliding from rest. If the
coefficient of kinetic friction between the box and the incline is
0.34 and the coefficient of static friction between the box and the
incline is 0.6, determine the time in seconds that it will take for
the box to reach the...

A hoop is released from rest at the top of a plane inclined at
29° above horizontal. How long does it take the hoop to roll 12.5 m
down the plane?
2.84s
4.66s
2.42s
2.26s
3.24s

A sphere is released from the top of a rough inclined plane. The
friction is sufficient so that the sphere rolls without slipping.
Mass of the sphere is M and radius is R. The height of the center
of the sphere from ground is h. Find the speed of the center of the
sphere as it reaches the bottom of the sphere.

A 40.0N box begins to slide from rest through a plane inclined at 25 degrees (with respect to the horizontal) and which has a length of 7.00m. The coefficient of kinetic friction between the box and the plane is 0.138. Determine:
a) the kinetic energy of the box when it reaches the end of the inclined plane
b) the kinetic friction force

A car stating from rest accelerates at 2 m/s2 for 5
seconds. The driver then maintians a steady speed for 12 seoncds.
The car the undergoes an accelration of -2.5m/s2 until
it reaches a speed of 4 m/s. A. what was the speed
of the car after 2 seconds? B. how far did the car
travel during the interval of constant speed? C.
how much time did the car spend slowing down? d.
what was the total distane the car...
