A 500 kg roller coaster car crests a 20m high hill at a speed of 10 m/s. It then rolls down the other side, all the way to ground level, and climbs a second hill. What is the speed of the car when it is 10 m up the second hill?

Step 1
First, we need to calculate the total mechanical energy of the roller coaster at the top of the first hill. The total mechanical energy is the sum of the kinetic energy and the potential energy. The kinetic energy (KE) is given by the formula KE = 1/2 * m * Show more…

A roller coaster car traveling at a constant speed of $20.0 \mathrm{~m} / \mathrm{s}$ on a level track comes to a straight incline with a constant slope. While going up the incline, the car has a constant acceleration of $0.750 \mathrm{~m} / \mathrm{s}^{2}$ in magnitude. (a) What is the speed of the car at $10.0 \mathrm{~s}$ on the incline? (b) How far has the car traveled up the incline at this time?
A 50 -kilogram roller coaster car is initially at rest at the top of a 25 -meter-high hill. When it is released, the car rolls down the hill and passes through a loop that has a radius of 10 meters. What is the change in potential energy as the roller coaster car moves from point $B$ to point $C ?$ (A) $1,000 \mathrm{J}$ (B) $2,500 \mathrm{J}$ (C) $5,500 \mathrm{J}$ (D) $10,000 \mathrm{J}$ (E) $20,000 \mathrm{J}$
A roller coaster is moving at $2.00 \mathrm{~m} / \mathrm{s}$ at the top of the first hill $(h=40.0 \mathrm{~m}) .$ Ignoring friction and air resistance, how fast will the roller coaster be moving at the top of a subsequent hill, which is $15.0 \mathrm{~m}$ high?
