Question

A bus traveling at 17 m/s accelerates at 3.5 m/s? for a time of 15 sec. What is the final velocity of the bus?

Answer 1

Step-by-step explanation:

The equation that relates final velocity to initial velocity, acceleration, and time is

`v_f=v_0+at` which states that the final velocity of an object is equal to the initial velocity plus the acceleration times the time. Filling in this formula with our givens:

`v_f=(17m)/(s)+(3.5m)/(s^2)(15s)` which gives us

`v_f=20.5(m)/(s)`
