Question

A ball that weighs 150g slides down a perfectly smooth incline at a starting height of 2.44 m at rest. Towards the bottom of the incline it strikes a 280g block and sticks. Both the ball and the block are able to move freely along the frictionless rollercoaster track. Can it make it over the first hill if the first hill is 23 cm high?

Answer #1

Final Answer:- it will make it over the first hill of height 23 cm

A block starting from rest at t = 0.0seconds slides down a
frictionless incline. during the time interval between t = 0seconds
and t = 1 seconds, the block travels 20 cm along the incline.
During the time interval between t = 1 second and t = 2 seconds,
the block travels how much CM??

A block of mass m = 2.10 kg slides down a 30.0∘ incline which is
3.60 m high. At the bottom, it strikes a block of mass M = 8.00 kg
which is at rest on a horizontal surface (Figure 1). (Assume a
smooth transition at the bottom of the incline.) The collision is
elastic, and friction can be ignored. Determine the speed of the
block with mass m = 2.10 kg after the collision. Determine the
speed of the...

1.A small block of mass 3.5 kg starting from rest slides down on
an incline plane of height 2.0 m, 40 degrees with respect to
horizontal (Fig. 2). The coefficient of kinetic friction between
the block and the incline plane is 0.25. At the end of the incline
plane, the block hits the top of a hemispherical mound of ice
(radius 1.0 m) , loses 75% of final kinetic energy (KE=0.5mv*v)
before the collision, then slide down on the surface...

A 9.0-kg box of oranges slides from rest down a frictionless
incline from a height of 5.0 m. A constant frictional force,
introduced at point A, brings the block to rest at point B. If the
coefficient of kinetic friction is 0.26, what is the distance
between A and B?

A 0.20-kg block slides from rest down a frictionless track from
a height of 1.5 m, and encounters a loop that is 1.0 m high. (a)
What is the speed of the block at the top of the loop? (b) The
block is slowed by a spring at the bottom of the track. If the
stiffness of the spring is 0.90 kN/m, how far does the block slide
before coming to rest?

A block of mass m = 1.50 kg slides down a 30.0∘ incline
which is 3.60 m high. At the bottom, it strikes a block of mass
M = 6.20 kg which is at rest on a horizontal surface
(Figure 1). (Assume a smooth transition at the bottom of the
incline.) The collision is elastic, and friction can be
ignored.
Part A
Determine the speed of the block with mass m = 1.50 kg
after the collision.
Express your answer...

A 500-g block is released from rest and slides down a
frictionless track that begins 2.26 m above the horizontal, as
shown in the figure below. At the bottom of the track, where the
surface is horizontal, the block strikes and sticks to a light
spring with a spring constant of 29.5 N/m. Find the maximum
distance the spring is compressed.
