A 1 kg toy car is propelled by a compressed spring that starts it moving. The car follows the curved track. What is the initial speed of the car that having gained 0.3 m in altitude has a speed of 2.0 m/s. You may assume the work due to friction along the track is 1 J.

A toy car of mass 1kg is pushed up against a spring with a spring constant of 500N/m, compressing the spring 0.05m. The spring is released, causing the car to slide across a frictionless track. After a certain distance of track, the car slides up a frictionless ramp of 10 degrees before coming to a stop. a) What is the speed fo the car after it leaves the spring but before it starts up the ramp. (Answer: 1.12m/s) b) What...

A 0.16 kg toy car has a spring-loaded bumper. The bumper has a constant of k = 1050 N/m. The toy is pressed against a wall and the spring compresses 5 cm. When the spring is released the car rolls on a flat surface and then up a hill. a) If there were no friction, how high up the hill should the car go?

A toy freight train consists of an engine and three identical cars. The train is moving to the right at constant speed along a straight, level track. Three spring scales are used to connect the cars as follows: spring scale A is located between the engine and the first car; scale B is between the first and second cars; scale C is between the second and third cars. (a) If air resistance and friction are negligible, what are the relative...

A .1 kg toy car with 0.01 kg, 0.01 m radius solid wheels is pushed into a spring with a 1 N/m spring constant until it has compressed by 0.02 m. The toy car is then released, after which it rolls without slipping on level ground. It is still attached to the spring, so its motion is harmonic (back and forth) motion. a. For this part assume that the mass of the wheels is zero: what is the frequency of...
