Question

23. Describe the motion of a body which is accelerating at a constant rate of 10 ms. If the body starts from rest.
how much distance will it cover in 2 s?
24. A motorcycle moving with a speed of 5 m/s is subjected to an acceleration of 0.2 m/s. Calculate the speed of
the motorcycle after 10 seconds, and the distance travelled in this time.
25. A bus running at a speed of 18 km/h is stopped in 2.5 seconds by applying brakes. Calculate the retardation
produced.
26. A train starting from rest moves with a uniform acceleration of 0.2 m/s squre for 5 minutes. Calculate the speed acquired and the distance travelled in this time.​

Answer 1

Answer:

The distance covered in 2 sec is 20 m.

Step-by-step explanation:

Given that,

Acceleration a = 10 m/s²

Initial velocity u = o

Time t = 2

Using equation of motion

....(I)

Where, u = initial velocity

s = distance

t = time

a = acceleration

We substitute the value in equation (I)

Hence, The distance covered in 2 sec is 20 m
