Q1. A cord passes over a weightless and frictionless pulley. Masses of 220 g and 389 g are attached to the ends of the cord. Find the distance the masses will move throughout the 5th second after they are started from rest.
Q2. You are trying to advance your shooting skills by shooting at a can on top of a fence post. You miss the can, and the bullet, moving at 207 m/s, is embedded 1.54 cm into the post when it comes to a stop. If constant acceleration is assumed, how long does it take for the bullet to stop?
Obtain an expression for the velocity
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
