Question

Consider a car that is initially traveling along a straight stretch of highway at 15 m/s. At t=0 the car begins to accelerate at 2.0 m/s2 in order to pass a truck. The final velocity is vx=25m/s. Calculate how far the car travels during its 5.0 s of acceleration.

Answer 1

Answer:

The car travels 100 meter during its 5.0 s of acceleration

Explanation:

We have the equation of motion v²=u²+2as, where v is the final velocity, u is the initial velocity, a is the acceleration ans s is the displacement.

v = 25 m/s

a = 2 m/s²

u = 15 m/s

Substituting

      25²=15²+2 x 2 x s

       s = 100 m

The car travels 100 meter during its 5.0 s of acceleration
