7.) A car starts from rest and accelerates

uniformly at 1.7 m/s/s. How long will it

take the car to reach a speed of 34 m/s?

A 200 s

B 58 s

C 20 s

D2 s

It will take 20 seconds for the car to attain a speed of 34 m/s

Explanation:

Acceleration of an object is given by a = velocity/time. Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time. Time = velocity/acceleration

= 34/1.7 = 20 s

So it takes 20 seconds to attain a speed of 34 m/s
