1. An x-ray tube accelerates electrons from rest at 5×10^14 m/s^2 through a distance of 15 cm.
Find(a) the electrons'velocity after this acceleration.
Find (b) the acceleration time. (Such high accelerations are possible because electrons are extremely light.)
2. A rock is launched straight up from the ground at 16.5m/s Graph the rock's velocity and position versus time from launch until it reaches the ground.
