Step 1
The potential energy at point A can be calculated using the formula: Potential Energy = mass * gravity * height Given that the mass of the roller coaster car is 500 kg and the height at point A is not provided, we cannot calculate the potential energy at this Show more…

A 250.0 kg roller coaster car has 20000 J of potential energy at the top of a hill. Neglecting frictional losses, what is the velocity of the car at the bottom of the hill?

A roller coaster car of mass 1000 kg is sitting on the first hill of a roller coaster ride as shown below. H = 100 m H = 40 m a. Draw the free-body diagram roller coaster car sitting on the first hill on the dot below. b. If the speed of the car on the second hill is 38 m/s (at h=40 m), how much energy was lost due to friction?

A car of mass $987 \mathrm{~kg}$ is traveling on a horizontal segment of a freeway with a speed of 64.5 mph. Suddenly, the driver has to hit the brakes hard to try to avoid an accident up ahead. The car does not have an ABS (antilock braking system), and the wheels lock, causing the car to slide some distance before it is brought to a stop by the friction force between its tires and the road surface. The coefficient of kinetic friction is $0.301 .$ How much mechanical energy is lost to heat in this process?
