This concludes the answers. If there is any mistake,
let me know immediately and I will fix
it....

A tennis ball on Mars, where the acceleration due to gravity is 0.379 of a g and air resistance is negligible, is hit directly upward and returns to the same level 9.20 {\rm s} later. How high above its original point did the ball go? and How fast was it moving just after being hit?
6. A tennis ball on Moon, where the acceleration due to gravity is 1/6 g (g- -9.8) and air resistance is negligible, is hit directly upward and returns to the same level 8.5 s later, (a) How high above its original point did the ball go? (b) How fast it moving just after it was hit?

On Mars, where the acceleration due to gravity is 3.8 m/s2, a 500 gram ball is thrown from a cliff that is 30 m above the ground at a speed of 22 m/s. The ball lands 45 m away from the base of the cliff. What is the speed of the ball just before it hits the ground?
