Numerical Problems

A bus is moving with the initial velocity 10 m/s. After 2 seconds, the velocity
becomes 20 m/s. Find the acceleration and distance moved by the bus.​

Answer 1

a = 5 [m/s²]

Step-by-step explanation:

To solve this problem we must use the following equation of kinematics.

`v_(f)=v_(o)+a*t`

where:

Vf = final velocity = 20 [m/s]

Vo = initial velocity = 10 [m/s]

t = time = 2 [s]

a = acceleration [m/s²]

Now replacing:

`20 =10 +a*2\\10=2*a\\a=5[m/s^(2) ]`
