Question

The initial velocity of an object is 20 m/s having retardation 2 m/s2. the distance moved by object in first three seconds is

Answer 1

Answer:

Answer should be 51m.

Explanation:

Given;

u= 20 m/s

a = (-2) m/S2

t= 3s.

By using the equation:

S = ut + 1/2 at^2

S = 20*3 + 1/2* (-2)*(9)

S = 60-9

S = 51 m.
