A dart is loaded into a spring-loaded toy dart gun by pushing the spring in by a distance ‘d’.  For the next loading, the spring is compressed a distance two times ‘d’. If the dart is shot straight up, how much higher will the dart travel the second time compared to the first? a. 4 times as high b. 1/4 as high c. 1/2 as high d. 2 times as high e. the same height

A wooden box of mass 6.0 kg slides on a frictionless tabletop with a speed of 3.0 m/s. It is brought to rest by a compressing spring. The spring content is 1250 N/m. a. Calculate the maximum distance the spring is compressed. b. Determine the speed and acceleration of the block who the spring is compressed a distance of 14 cm.

A 3.59 kg ball is held at rest exactly 3.7 meters in the air. Assume their is no spring in this problem. A. How much gravitational potential energy does the ball currently have? Joules B. How much kinetic energy does the ball currently have? Joules C. How much total mechanical energy does the ball have currently? Joules The ball is than allowed to fall to the ground. As the ball falls It gravitational potential energy gets converted into Kinetic Energy. The moment before hits the ground all of its energy is in the form of kinetic energy. D. How much G.P.E does the ball have the moment before it hits the ground? Joules E. How much kinetic energy does the ball have the moment before it hits the ground? Joules F. what is the ball's speed the instant before it hits the ground? m/s

A 2.75 kg mass is pressed against a horizontal spring (k = 325 N/m) on a frictionless surface. If the block is pulled 6.5 cm from its equilibrium position and then released,   A. What is the potential energy stored in the spring?   B.What is the speed of the block when its released
