Question

The velocity of a diver just before hitting the water is -10.9 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.17 s of the dive?

Answer 1

velocity of the diver is vertically downwards

given that

`v = -10.9 m/s`

time of motion of the diver

`t = 1.17 s`

so the displacement is given by

`d = v*t`

`d = -10.9 * 1.17`

`d = -12.75 m`

so it will be displaced downwards by 12.75 m
