Question

A car has a uniform acceleration of 4m/sec^2 find the spped acquired by the car 10 seconds after the start

Answer 1

Answer:

40 m/s

Explanation:

According to the given question,

u = initial velocity = 0 m/s (After start)

a = acceleration = 4 m/s^2

t = time = 10 sec

v = final velocity = ?

We are asked to find the final velocity of the car after it starts from rest.

We know,

• v = u + at

(Putting the values of a, t and u we get)

• v = 0+4×10

• v = 40 m/s ans.

Hence, the car will be at the velocity of 40 m/s after 10 sec with acceleration of 4m/s^2 from its initial position.
