30 m/s

Use the kinematic equation:

vf=vi+at,

where:

vf is the final velocity, vi is the initial velocity, a is the rate of acceleration, and t is the time interval.

Known

vi = 0 m/s

a = 6 m/s2 = 6 m/s/s

t = 5 s

Unknown

vf

Solution

Plug in the known values and solve.

#vf = 0 + 6 m/s/s x 5s = 30 m/s

Use one of Newton's equations of motion:
v = u + at
where:
• v = final velocity (to calculate)
• u = initial velocity = 0 m/s as it starts from rest
• a = (constant) acceleration = 6 m/s²
• t = time = 5 s
v = 0 m/s + 6 m/s² × 5 s = 30 m/s

A race car accelerates from rest at a rate of 6m/s^2. How fast will the car be going after 5 seconds?

i dont get it but heres mineΒ What is the average acceleration of a car that goes from 75 km/h to rest in 5 seconds?
