Question

a driver accelerates car at first 4m/s and then at the rate 8m/s. Calculate the ratio of the forces exerted by the engines
​

Answer 1

Explanation:

the ratio between them is 1:2

Answer 2

Answer:

Force is that which changes or tries to change the state of rest or of uniform motion of a body in a straight line.

1 : 2

Force when the car accelerates at 4 m/s²

━━━━━━━━━━━━━━━━━━━━━━━━━━

━━━━━━━━━━━━━━━━━━━━━━━━━━

= 4 × m = 4m Newton

Force when car accelerates at 8 m/s²

━━━━━━━━━━━━━

= 8 × m = 8m Newton

$ratio$

$\frac{4}{8 } = 4:8$
