A jeep runs around the curve of radius 0.3 km at a constant speed of 60 ms -1 . The resultant change in velocity, instantaneous acceleration and average acceleration over 60 0 arc are
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ Δ 
= 2 × 60 sin 30 = 60 ms -1
Instantaneous acceleration
= 
Time taken to cover the arc
= t = 
using Δ Δ t = 
∴ ∴ average acceleration a = 
=
