The two dynamics carts, one single cart of mass 1.0 kg, the other a double cart of mass 2.0 kg, each with essentially frictionless wheels, are in contact and at rest. The compression spring on the single cart is suddenly released, causing the cart to exert an average force of 2.0 N [E] on the double cart for 0.50 s Q4. The velocity of the double cart exactly 0.20 s after the compression spring is released is a) 0.25 cm/? [E] c) 4.0 cm/? [E] b) 1.0 cm/? [E] d) zero e) less than 0.25 c m/? [E], but greater than zero Q5. After the spring is complete and the carts are separated, the net force acting on the single cart is a) 19.6 N [down] c) 19.6 N [up] b) 2.0 N [W] d) zero e) the vector sum of 19.6 N [down] and 2.0 N [W]

The system composed of two springs and a particle with mass ? shown in the figure can beconsidered as a system with a single equivalent spring. Suppose you move the particle and stretchboth springs (since the force constants are not the same, it cannot be assumed that both springs arestretch the same, you must find a relationship between how much each spring stretches and the displacement of the spring.particle). Determine an expression for the equivalent spring constant in terms of the constantsof each spring.
Mickey, a daredevil mouse of mass 0.0201 kg,0.0201 kg, is attempting to become the world's first "mouse cannonball." He is loaded into a spring‑powered gun pointing up at some angle and is shot into the air. The gun's spring has a force constant of 87.5 N/m87.5 N/m and is initially compressed a distance of 0.145 m0.145 m from its relaxed position. If Mickey has a constant horizontal speed of 2.15 m/s2.15 m/s while he is flying through the air, how high ℎh above his initial location in the gun does Mickey soar? Assume ?=9.81 m/s2.

A 10.0 g bullet is fired into and embeds itself in a 2.30 kg block attached to a spring with a spring constant of 19.8 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block, and the block slides on a frictionless surface? (Note: You must use conservation of momentum in this problem.) m
