Question

1. A car starting from rest accelerates uniformly at 3

Answer 1

The car's final speed in  m/s after the acceleration is 30.

Given the following data:

• Initial velocity, U = 0 m/s (since the cars starts from rest)

• Time, t = 10 seconds

• Acceleration, a = 3 meter per seconds square.

To find the car's final speed in  m/s after the acceleration, we would use the first equation of motion;

Mathematically, the first equation of motion is given by the formula;

$V = U + at\\\\V = 0 + 3(10)$

Final speed, V = 30 m/s

Therefore, the car's final speed in  m/s after the acceleration is 30.
