Question

a car moving at 10 m/s speed up uniformaly to a speed of 30 m/s in a time of 5 seconds. what was the car's acceleration?​

Answer 1

Answer:

acceleration = final velocity-initial velocity/time

so

acceleration= 30-10m/s÷5s

= 20m/s÷5s

=4m/s²

Answer 2

Given:-

• Initial velocity ,u = 10m/s
• Final velocity ,v = 30m/s
• Time taken ,t = 5s

To Find:-

• Acceleration ,a

Solution:-

According to the Question

It is given that car moving at 10 m/s speed up uniformaly to a speed of 30 m/s in a time of 5 seconds.

we have to calculate the acceleration of the car .

As we know that acceleration is defined as the rate of change in velocity.

• a = v-u/t

where,

• v is the final velocity
• a is the acceleration
• u is the initial velocity
• t is the time taken

Substitute the value we get

→ a = 30-10/5

→ a = 20/5

→ a = 4m/s².

• Hence, the acceleration of the car was 4m/s².
