Question

body at time t = 2 s
The acceleration a of an object at time t is given by a = 2t. If initial velocity of the object is 2 m/s, t
its velocity after 5 s. 27 mis​

Answer 1

Answer:

23.08m/s

Explanation:

v=u+at (v after 5.27 sec)

v=2+{(2×2)×5.27 } (a=2t, at t=2sec)

v=2+{4×5.27}

v=23.08m/s
