You will be hiking to a lake with some of your friends by following the trails indicated on a map at the trailhead. the map says that you will travel 4.00 mi directly north, then 5.31 mi in a direction 35.0° east of north, then finally 1.10 mi in a direction 15.0° north of east. assume north to be +y and east to be +x. find the direction of the displacement vector for the hike. enter the answer as an angle north of east.

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?
