1.	When a car driver travelling at a speed of 10 ms applies brakes and brings the car to rest in 20s, then retardation will be : (a) + 2 m/s2 (b) −2m/s2 (c) −0.5m/s2 (d) +0.5m/s2
Answer» When a car driver travelling at a speed of 10 $\frac{m}{s}$ applies brakes and brings the car to rest in 20s, then retardation will be : (a) $+ 2 m / s^{2}$ (b) $- 2 m / s^{2}$ (c) $- 0.5 m / s^{2}$ (d) $+ 0.5 m / s^{2}$

When a car driver travelling at a speed of 10 ms applies brakes and brings the car to rest in 20s, then retardation will be : (a) + 2 m/s2 (b) −2m/s2 (c) −0.5m/s2 (d) +0.5m/s2

Answer»

When a car driver travelling at a speed of 10 $\frac{m}{s}$ applies brakes and brings the car to rest in 20s, then retardation will be :

(a) $+ 2 m / s^{2}$ (b) $- 2 m / s^{2}$ (c) $- 0.5 m / s^{2}$ (d) $+ 0.5 m / s^{2}$
