Question

1) a car moving with a velocity of 30 m/s is subjected to uniform retardation of 3m /s2 .the time taken by the car to come to rest is
A)5 s
B) 10 s
C) 15 s
D) 20 s

A bus is moving with a constant speed of 75 kmph .the driver observes the red signal and applies the brakes. If the speed of the bus reduces uniformly to 21kmph in 3s find the retardation produced in the bus A)3m/s
B) 4m/s2
C) 5m/s2
-D) 6m/s2

11. The speed of a body which is moving with constant acceleration changes
5m/s to 15m/s in 5s. Find the displacement of the body.
A) 50m
B) 100m
C) 150m
D) 200m
12. A body moving with acceleration covers a displacement of 5m in 2s. Find
velocity after 2s if its initial velocity is 1m/s.
A)2m/s B) 3m/s
C) 4m/s
D) 5m/s
13. A uniformly accelerated car is found to possess the velocities 12.5 m/s and 135
kmph at two different places in its path. If the car takes 10 min to travel
these places, find the distance between them.
A) 25km . B) 30km
C) 5km
D) 15km
14. A cyclist moving with an initial velocity of 4 m/s is uniformly accelerate
3m/s2. Find the distance travelled by the cyclist in 6s.
A)78 m
B) 58m
C) 38m D) 98m​
