A motorcycle starting from rest is uniformly accelerated such that its velocity in 10s is 72kmhr¯¹. What is its acceleration?
A. 108ms-2 B. 86ms-2 C. 4ms-2 D. 2ms-2 Correct Answer: Option D = 2ms-2 Explanation where u = o m/s, t = 10s, v = 72kmhr−1 —> (72 X 1000) / 3600 : v = 20 m/s Acceleration (a) = ( v – u ) / t —> (20 – 0) / 10 : a =...
