A. Release a ball from rest near Earth’s surface.
B. Release a toy car from rest such that it travels along different looped sections of a track.
C. Launch a water-propelled rocket from rest such that it travels into the air and falls back to Earth’s surface.
D. Release a cart from rest such that it travels down an incline of 40° with respect to the ground.

Answer 1

Dear student Concept:

The acceleration due to gravity near the earth surface is almost constant and equal to g=9.8m/s2 Here the option A and D ar... More
