A car accelerates uniformly in a straight line from rest at the rate of 3.3 m/s^2
What is the speed of the car after it has
traveled 60 m?
h
Answer in units of m/s.

how Long does it take the car to travel 60m?
answer in units of s

see below

Explanation:

The intial speed is u=0

The acceleration is a= 3.3

The distance is s=60m

Apply the equation of motion

=+2as

So,

=0+2*3.3*60=396

v= = 19.89 m/s ≈20 m/s

Applying the equation of motion

v=u+at

t= = = 6.02seconds

it is called kinetic energy

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
