Q1. A ball of mass 60 g is dropped from a height of
3.4 m. It lands on the top of a frictionless ramp at height 1.8 m.
The ramp is tilted at an angle of 20 degrees.
(a) What is the velocity of the ball at the top of the
ramp?
(b) At the bottom of the ramp it collides with and
sticks to a ball of mass 73 g. What is their velocity after the
collision?
(c) The stuck together balls collide with a spring of
spring constant 300 N/m. How much will they compress it?
(d) They then go back up the ramp. How high will they
go?
A ball with mass of 0.050 kg is dropped from a height of 2.0 m. It collides with the floor, then sticks to the table. The Collison takes 0.020 s. a) Use the conservation of mechanical energy (Ei = Ef) to calculate the velocity of the ball before collision with the floor
A 4.00 kg ball is dropped from a height of 15.0 m above one end of a uniform bar that pivots at its center. The has mass 9.00 kg and is 4.00 m in length. At the other end of the bar sits another 4.00 kg ball, unattached to the bar. the dropped ball sticks to the bar after the collision. Assume that the bar is horizontal when the dropped ball hits it. How high will the other ball go...
A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?
Ablock of mass m,-1.9 kg is held againsta spring ofspring constantk=410 N/m and compressedx frictionless surface towards mass m2 4.3 kg. The two masses collide and mass mi rebounds back towards the spring at a speed of 2.1 m/s, while mass m2 slides up the frictionless hill. 3/ 0.75 m. When released, it is pushed along the a. What is the speed of mass mi right before the collision? b. What is the speed of mass m2 after the collision?...

A ball with a mass of m 0.175-kg is dropped from a height of h 2.50 m It rebounds to a height ofh2- 2.00 m (a) Using energy method to find the velocity (magnitude and direction of the ball immedately before hiting the floor? (b) Using energy method to find the velocity (magnitude and drection) of the ball immed iately aftfer hitting the floor? (c) If the collision between the ball and the floor lasts for Δt-0.015 sec, using...
A 5.00 kg mass is dropped from a height 2.00 m above the top of a spring. The mass lands on the spring and compresses it 30.0 cm before momentarily coming to rest. Ignoring air resistance, determine the spring constant for the spring.
A mass m is dropped from rest from a height h above the left hand side of a frictionless bowl where it meets the side of the bowl exactly after falling h and starts to slide down the side of the bowl with some initial velocity where it then collides with a 4m mass sitting at the bottom. The 4m mass makes it exactly up to the rim of the bowl on the right hand side and the m mass...
A soft tennis ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.03 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. -Answer is 4.49 m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms. (d) How much did the...
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.13 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor, in m/s. (b) Calculate its velocity just after it leaves the floor on its way back up, in m/s. (c) Calculate its acceleration (in m/s^2) during contact with the floor if that contact lasts 3.50 ms. (d) How much...
