The largest passenger ship still in service is the SS Norway, which has a mass of 7.6 x 10' kg. The force required to accelerate the SS Norway from rest to its top cruising speed of 33 km h is 1.6 x 10" N assuming that this acceleration takes place over a distance of 2.0 km. Ilow much work must be done on the sluip during this period of acceleration?​

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?
