Question

. A car goes around at 20 m/s. The radius of curvature is 50 m. Calculate the centripetal acceleration?

20 m/s²
10 m/s²
8 m/s²
16 m/s²

Answer 1

here, V= 20 m/s

r= 50 m

formula for centripetal acceleration= V^2/r

=(20)^2/50

= 400/50

= 8m/s^2

therefore the centripedal acceleration is 8m/s^2
