A 12 kg block is pressed against a spring with spring constant k = 1424 N/m....
A 12 kg block is pressed against a spring with spring constant k = 1424 N/m. The spring is normally 65 cm long but the block is pressed against it to compress the spring until it is only 27 cm long. The block is then released and the spring pushes it forward onto a frictionless surface. a)How fast is the block moving immediately after it leaves the spring? b) The mass then slides across a 2.5 m wide surface with...

A toy car of mass 0.620 kg is pressed against a spring. The spring constant is 250 N/m and the spring is compressed a distance of 0.031 m. How fast is the cart moving after it's released from the spring? Ignore the effects of friction.

7: A 60-kg box is placed against a uniform spring with a spring constant (k) of 3300 N/m The box is pushed to the right so it compresses the spring 25-cm. When the box is released, it is propelled to the left. (a) What is the velocity of the box as it slides along the flat surface to the left after it loses contact with the spring? 350 (b) How far up the ramp will the box slide while coming...

A 50g toy car is spring loaded to propel forward when released. If the spring is stretched a distance of 2cm and has a K value of 500N/m. Calculate the speed at which the toy will move when the spring is released.

7. A 1300 kg car drives up a 17 m high hill (the elevation of the hill is 17 meters). During the drive two nonconservative forces do work on the car: the force of friction and the force generated by the car’s engine. The work done by friction adds 331 kJ to the internal energy. The work done by the engine is 634 kJ. (a) What is the change in the car’s kinetic energy? (b) If the car started up...

An 18000 kg freight car rests against a spring bumper at the end of a railroad track. The spring has constant k=3.2×10^5 N/m. The car is hit by a second car of 9400 kg mass moving at 8.0 m/s , and the two couple together. Find the maximum compression of the spring. Find the speed of the two cars when they rebound together from the spring.

A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...

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...
The toy gun in the figure below consists of a spring with spring constant k
The toy gun in the figure below consists of a spring with spring constant k. It is loaded with a projectile of mass m and the spring is compressed a distance d. The toy gun is fired horizontally and the bullet travels a total distance L within the toy gun before it is released. A) Neglecting all resistive forces, determine the speed of the projectile vo once it exits the toy gun (i.e., express Vo in terms of the known quantities...

A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....
