Question

) A car starting from rest accelerates at a rate of 10n/s and reaches
to a velocity of 75m/s. Find the time taken​

Answer 1

Using the expression:

Acceleration = v2 - v1 / t

Putting the values of the given parameters in the question we get

10 = 75 - 0 / t

t = 75/10

t = 7.5 secs

Answer 2

Answer:

7.5s

Explanation:

u (initial velocity) = 0 m/s

a ( acceleration ) = 10 m/s

v ( final velocity ) = 75 m/s

using first equation of motion,

v = u + at

= 75 = 0 + 10t

= 75 + 10t

= 75/10 = t

= 7.5 = t

Therefore, t = 7.5 m/s
