Question

If initial speed of body is zero. After 3 second speed will become 3 m/s. Find the acceleration ?

Answer 1

Answer:

v =  u + at

3 = 0 + a (3)

hence a = 1

Explanation:

Answer 2

Explanation:

If a particle has an initial velocity of 6 m/s and a constant acceleration of −2 m/s2, then: when t =1 ... m/s. Find the velocity of the particle: ... After 3 seconds, the velocity is 4.5+3×1.5=9 m/ s.
