Consider two cases in which cart A moves to the left with momentum \vec{p}_ip → i and then collides with a second cart which is initially at rest on a horizontal, frictionless air track. In case 1, cart A moves to the left after the collision at a speed of 1 m/s. In case 2, cart A moves to the right after the collision with the same speed as in case 1 (1 m/s). After the collision, the magnitude of the second cart's momentum in case 1 is the magnitude of the second cart's momentum in case 2.

Aspring with an unstrained length of 0.071 m and a spring constant of 2.6 n/m hangs vertically downward from the ceiling. a uniform electric field directed vertically upward fills the region containing the spring. a sphere with a mass of 5.29 10-3 kg and a net charge of +7.2 µc is attached to the lower end of the spring. the spring is released slowly, until it reaches equilibrium. the equilibrium length of the spring is 0.058 m. what is the magnitude of the external electric field?
