A toy car has a 50g body and four solid wheels, each with a mass of 5g and a radius of 7 mm. The car rolls down a horizontal track at 2 m/s, and at the end of the track it runs into a spring. If the car compresses the spring by 1 cm before bouncing back, what is the spring’s spring constant? Answer: 2400 N/m

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...

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 150.0 kg cart rides down a set of tracks on four solid steel wheels, each with radius 20.0 cm and mass 45.0 kg. The tracks slope downward at an angle of 24 ∘ to the horizontal. If the cart is released from rest a distance of 23.5 m from the bottom of the track (measured along the slope), how fast will it be moving when it reaches the bottom? Assume that the wheels roll without slipping, and that there...

A toy cart consists of a 1.00 kg block and four solid rubber wheels 200 g each. The cart is released from rest at the top of an inclined plane at a height of 46.0 cm above the ground, as shown. Determine the speed near the bottom of the incline when a. the cart is placed on its back (wheels up) and slides down without friction. the cart rolls down without slipping. 46 cm

2. A toy car has a mass of 0.400 kg. It gets thrown at 9.0 m/s toward a spring-held block with a mass of 1.1 kg. As a result of the impact, the car bounces backward from the block. It does not stick. The block compresses the spring by a maximum distance of 24 cm. After it bounces, the car is traveling 1/3 as fast as it was before it hit the block. It does not stick What is the...

A solid uniform sphere of radius 0.76 cm and a mass of 0.87 kg is held against a spring compressed a distance of 6.0 cm from its resting length. After release, the sphere leaves the spring and rolls down the flat, horizontal table with a translational velocity of 3.9 m/s. a) What is the force constant of the spring? b) If the ball then rolls up a ramp inclined at 22 degrees, how far along the ramp does it travel?

2m 20 1m You have built an enormous spring-loaded Hot Wheels track that will propel a 50 gram toy car through a loop and launch it across the room. The spring constant is 800 N/m, the spring launcher has an initial spring displacement of 5 cm. What is the maximum radius R of the loop such that the car moves around the loop without falling off at the top, so that the toy car can make to the end point...

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 roller coaster car has a mass of 800 kg. It is launched horizontally from a giant spring (spring constant 35 kN/m), rolls 10m and then goes through a vertical loop-the-loop track of radius 7 m. On average, for every meter the car rolls on the track, thermal energy increases by 800 J. The designer, who wants to go home for the weekend, says that compressing the spring 3 m should give the car enough energy to safely go...
