The initial velocity of a car is 10 m/s to the north. The car undergoes an acceleration of 2 m/sto the north for 4 seconds. What is the
car's new velocity?

Answer:

18m/s

Explanation:

Given parameters;

Initial velocity  = 10m/s

Acceleration  = 2m/s²

Time = 4s

Unknown:

Car's new velocity  = ?

Solution:

We use one of the kinematics equation to solve this problem:

          v  = u + at

v  = new velocity

u = initial velocity

a = acceleration

t = time

      v = 10 + (2 x 4)  = 18m/s
