Question

the acceleration of a particle in m/s2 is given by a = 18t2 + 36t + 120. if the particle starts from rest and velocity at the end of 1 sec is ​

Answer 1

Answer:

v = u +at

v= 0 + 18 (1)^2+ 36(1) + 120

v = 18+36+120 = 174 m/s2

Answer 2

Answer:

the answer is 144 m/s.you need to integrate to get ans.
