A moving body is covering the distance directly proportional to the square of time.The tangential acceleration of the body is?
Answered by admin @
Answer:
Hope it Helps plz mark me brainliest
Explanation:
According to question, distance covered by body is directly proportional to square of the time. e.g.,
, k is proportionality constant.
differentiate with respect to t,
again differentiate with respect to time,
here d²x/dt² is what ? of course acceleration
hence, it is clear that acceleration = 2k = constant
therefore option (c)is correct choice
