A particle decelerating to rest has its speed v m/s at time t seconds given by: v = 6t - ½ t².
The deceleration of the particle when v = 10 is:.
10 m/s².
-10 m/s².
4 m/s².
-4 m/s².
A car accelerates uniformly from a velocity of 10 m/s to 60 m/s in 6 seconds on a straight road.
The distance it covered is:
150 m.
215 m.
210 m.
200 m.
