Question

a body starts from rest and moved 150 in 12 second find the acceleration of the body and its velocity ​

Answer 1

Answer:

The initial velocity of the object (u) = 0 m/ s

The distance moved by the object (S) = 150 m

Time taken (t) = 12s

FINDING ACCELERATION :-

Using the formula -

S = ut + 1/ 2 at²

=> 150 = 0×12 + 1/ 2 × a × (12)²

=> $150 = \frac{1}{2} * a * (12)^{2}$

=> $a = \frac{150 * 2}{12 * 12}$

=> a = 25/ 12

=> a = 2.08 m/s²

FINDING VELOCITY :-

Using the formula -

v = u + at

=> v = 0 + (25/ 12) x 12

=> v = 25 m/ s
