Two tug boats push on a barge in a bay with mass 61,014kg as seen in the picture below. If one barge pushes east with a force of F1 = 50,597N, one
pushes north with a force of F2 = 32,351N and the third pushes at an angle of
35 degrees above the horizontal with a force of 12,000N. Find the resulting
acceleration of the boat

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?
