Question

The space shuttle undergoes an acceleration of 53.9 m/s2. How fast is it traveling at the end of 55.2s

Answer 1

Answer: 2975,28m/s

In this case, you asked how much the speed and given the acceleration rate and the time. Speed is acceleration x time, so you just need to multiply the both number. The equation would be: 

Velocity = acceleration x time
Velocity = 53.9 m/s2 x 55.2s= 2975,28m/s
