A 95.7 kg cart initially sits at rest on a flat track. This cart of charge 0.006 C is placed in an initial potential of 276,228 V, which launches it toward a spring with a spring constant of 416.2 N/m. After being launched, the cart crashes into the spring that brings it to a stop. How far is the spring compressed in order to stop the cart?

-A roller coaster cart of mass (m1=127 kg) initially sits at rest on a track. Once the motor is activated, the cart is accelerated forward (across level ground) until it reaches the bottom of a giant circular loop with a radius of (r1=17.5 m). At this point, the motor is turned off and the cart must "coast" for the remainder of the ride. Assume the track is frictionless and ignore air resistance. At the top of the loop, what is...

A 1.0-kg standard cart collides on a low-friction track with cart A. The standard cart has an initial xcomponent of velocity of +0.40 m/s, and cart A is initially at rest. After the collision the x component of velocity of the standard cart is +0.20 m/s and the x component of velocity of cart A is +0.70 m/s . After the collision, cart A continues to the end of the track and rebounds with its speed unchanged. Before the carts...

A rocket sits initially at rest on the surface of the earth, until it begins burning its engines. While burning its engines, it accelerates upward at 30.0 m/s2 for 30.0 s. It then runs out of fuel and continues ascending to its maximum height in free fall. Ignoring air resistance, (i) what is the rocket’s maximum altitude, and (ii) how much time passes from liftoff to reaching its maximum altitude?
