(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A diver jumps off a 5m high diving board. The diver enters the water 1.5seconds later. Taking g=10m/s^2 determine

(a) the speed he generates in his jump

(b)his maximum height measured from the top of the diving board

(c) the speed with which he enters the water

2. Relevant equations

v = u + at

s = u + 1/2 a t^2

v^2 = u^2 + 2as

3. The attempt at a solution

stuck on part (a) don't know if the force of gravity will be positive or negative since he is jumping.

s = ut + 1/2 at^2

s = 1.5(u) +1/2(-10) (1.5^2)

5 = 1.5u - 5(2.25)

5 = 1.5u - 11.25

16.25 = 1.5u

u = 10.83 m /s
