Yosemite Sam was sailing his ship at a speed of 67 m/s when suddenly a storm accelerated his boat at a rate of 5.4 m/s^2 over a time period of 55s. What was Sam’s final velocity ? What formula must be used?

Respuesta :

Answer: vf= 364 m/s

Explanation: Use the formula for acceleration:

a= vf - vi / t

Derive for vf:

vf =( at )+ vi

= 5.4 m/s² ( 55s) + 67 m/s

= 364 m/s
