What is acceleration for the first 10 seconds? Use that a to find the speed of the particle when t = 10 seconds, v(t=10)? b) What is the position of the of the particle when t = 10 sec,
x(t=10)?
c) From 10 to 15 seconds, what is a? So what is v?
d) How far does the particle move between 10-15 seconds?
e) From 15 to 20 seconds, how far does the particle move?
f) What is the speed when t = 20 sec?

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?
