Question

A car moving with the speed of 10m/s takes a
circular turn of radius 20 m. The magnitude
the acceleration of the car is
(1) 5.0 ms-2
(2) 50.0 ms-2
(3) 0.25 ms-2
(4) 0.5 ms-2​

Answer 1

A car moving with the speed of 10m/s takes a circular turn of radius 20 m. The magnitude the acceleration of the car is

(1) 5.0 ms-2

(2) 50.0 ms-2

(3) 0.25 ms-2

(4) 0.5 ms-2

answer : option (1) 5.0 m/s²

explanation : A car moving with the speed of 10m/s takes a circular turn of radius 20 m.

centripetal acceleration , α = v²/R

where R = 20m , v = 10 m/s

α = (10)²/20 = 5 m/s²

hence, the magnitude of the acceleration of the car is 5m/s²

so, option (1) is correct choice.
