How far will a body move in 4 seconds if uniformly accelerated from rest at the rate of 2 ms-2?

Answer Details

The formula for distance traveled by a body with uniform acceleration is given by: distance = (1/2) × acceleration × time² Given that the body starts from rest (initial velocity = 0), and the acceleration is 2ms⁻², and the time taken is 4 seconds, we can substitute these values in the above formula and get: distance = (1/2) × 2ms⁻² × (4 s)² = 16 m Therefore, the distance moved by the body in 4 seconds is 16 meters. Hence, the answer is option (iii) 16m.
