An astronaut, while on the Earth, gives a good kick to a soccer ball. The ball lands in tę seconds after the kick. The astronaut then takes the ball to the Moon where she gives it a somewhat weaker kick. As a result, the ball reaches exactly the same maximal height it reached previously on the Earth. What statement is true about the time tm that the ball spent aloft on the Moon? (The gravity on th Moon is 6 times weaker than on the Earth. You can rely either on a direct calculation, or on a dimensional analysis or both) A. tm=36 te
B. tm=12te
C. tm=te
D. tm=(6)^1/2 te
Е. tm=6te

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s. when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
