## Question:

A triple jumper needs a velocity of 8.4 m/s to make a good jump. If he is accelerating at 4.6 m/s{eq}^2 {/eq}, how much time does he need to reach the velocity?

## Kinematic Equations:

Kinematic equations allow us to find the parameters that describe the motion of an object. These parameters include the speed, distance and acceleration. The acceleration of a body is the change in the velocity of a body per unit time.
