Question

If a car accelerates uniformaly from rest and attains a
speed of 40 m/s in 10 seconds, it covers a distance of
(a) 200 m
(b) 300 m
(c) 356 m
(d) 142 m​

Answer 1

Answer:

200 m is the correct answer to this question

Answer 2

Given,

Initial velocity(u) = 0 m/s

Final velocity(v) = 40 m/s

Time taken = 10 seconds

To Find,

The distance covered by the car.

Solution,

First, we will calculate the acceleration of the car

a = (v-u)/t

a = 40/10

a = 4 m/s²

Now, using the equation of motion

S = ut+1/2 at²

S = 1/2*4*10*10

S = 200 m

Hence, the correct answer is option (a) 200 m.
