Question

2.39 A tennis ball on Mars, where the acceleration due to ma gravity is 0.379g and air resistance is negligible, is hit directly up- th ward and returns to the same level 8.5 s later. (a) How high above v its original point did the ball go? (b) How fast was it moving justi after it was hit? (c) Sketch graphs of the ball's vertical position, vertical velocity, and vertical acceleration as functions of time while it's in the Martian air. dasuinon the Mon A unar lander is making

Answer 1

Concept : here we use equations of kinematics for motion in one dimension under gravity as shown below ,
