A 0.54 kg block is held in place against the spring by a 65-N horizontal external force. The external force is removed, and the block is projected with a velocity v1 = 1.2 m/s upon
-separation from the spring. The block descends a ramp and has a velocity v2 = 1.4 m/s at the
bottom. The track is frictionless between points A and B. The block enters a rough section at
B, extending to E. The coefficient of kinetic friction is 0.36. The velocity of the block is
v3 = 1.4 m/s at C. The block moves on to D, where it stops. In Fig. 7.4, the initial compression
of the spring, in cm, is closest to: Hint: use hooke's law and substitute k into the spring
energy equation.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
