Question

A car accelerates uniformly from 5 m/s to 10 m/s in 5 seconds. Find its acceleration.​

Answer 1

Answer:

37.5 is the answer...

Explanation:

Using Newton's third equation of motion i.e.

v² - u² = 2as

For this problem :

Final velocity (v) = 10 m/s

Initial velocity (u) = 5 m/s

Constant Acceleration (a) = ∆v/∆t = (10–5)/5

Hence a = 1 m/s²

Substituting these values in the equation :

10² - 5² = 2 *(1) s

75 = 2 s

s = 37.5 m

Answer 2

Answer:

1m/s^2

Explanation:

u= 5m/s

v= 10m/s

t= 5 sec

a= v-u/t

  = 10-5/5

  = 5/5

  = 1 m/s^2
