Question

. While traveling at 10 m/s Billy decides to speed up. He accelerates for 5 seconds with a

rate of 3 m/s?. Calculate the velocity he will have at the end of the acceleration.

Answer 1

Using the kinematic equation for velocity, Billy's final velocity after accelerating at 3 m/s² for 5 seconds, starting from 10 m/s, is found to be 25 m/s.

Step-by-step explanation:

To calculate the velocity that Billy will have at the end of his acceleration, we use the formula v = u + at, where:
v is the final velocity,

u is the initial velocity,a is the acceleration, andt is the time.

Billy's initial velocity (u) is 10 m/s, his acceleration (a) is 3 m/s², and the time (t) is 5 seconds. Plugging these values into the formula gives:

v = 10 m/s + (3 m/s² × 5 s)

v = 10 m/s + 15 m/s

v = 25 m/s

Therefore, at the end of the acceleration, Billy's velocity is 25 m/s.
