Question

a particle moves with acceleration a equals 4t+2 m/s2.Find its displacement at t=4 sec if at origin its velocity was2m/s at start of motion​

Answer 1

Explanation:

u= 2m/s

t= 4s

a= 4t + 2 = 4(4) + 2 = 16 + 2 = 18 m/s^2

s = ut + 1/2 a t^2

= 8 + 9 * 16

= 8 + 144

= 152 m

HOPE THIS WILL BE HELPFULL

PLEASE MARK ME AS BRAINLIEST PLEASE!!!!!!!!!!!!!!

Answer 2

Answer:

the answer is 152 m......
