Question

A body moving with a constant acceleration travels to distance 3 metre and 8 metre respectively in one second and two second calculate the initial velocity and acceleration of the body ​

Answer 1

$s = ut + \frac{1}{2} {at}^{2}$

$3 = u \times 1 + \frac{a}{2} \times 1$

2u + a = 6 ------------- (1)

$8 = u \times 2 + \frac{a}{2} + {2}^{2}$

2u + 2a = 8 ----------- (2)

(2) - (1)

A = 2m/s

From (1)

2u + 2 = 6

U = 2m/s

Answer 2
