What is the formula for displacement? ∆ = xf − xi
v = /
v = ∆/
∆ = v ∙ t
Choose all that apply

What are two different ways you could find the value of a? explain these methods.

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?

You can melt ice by applying pressure because the solid/liquid line has a slope.
