A stone is thrown off of a cliff 4.79 m tall. The initial velocity is 8.6 m/s at an angle of 58.33◦ from the
upward vertical direction. (a) What is the velocity (speed and direction) at the highest point? (b) When
does the stone reach the highest point? (c) What is the velocity (speed and direction) when the stone
lands? (d) When does it land?

the answer to your question is high voltage and high currency

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
