Answer:
The velocity of the particle = -1.92 m/s
The speed of the particle = 5.72 m/s
Explanation:
Given equation of motion;

Velocity is defined as the change in displacement with time.

The distance traveled by the particle in 5 s:

The speed of the particle when t = 5s

Answer:
Option (a)
Explanation:
Given that,
Mass of a car, m = 1200 kg
Force exerted by the engine, F = 600 N
Noe force,F = ma
a is the acceleration of the engine

So, the acceleration of the car is 0.5 m/s².
