Question

A body moves with an initial velocity of 40m/s and its accelerates uniformly until it attains a velocity of 80m/s,it then continues at that velocity for some time and then decelerate uniformly to rest

Answer 1

Answer:

Explanation:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
