Question

The car starts from rest and accelerate with rate of 4 m/s² in 10 seconds. How far does the car travelled? ​

Answer 1

Answer:

v = 44 m/s

Explanation:

Given Values:

a = 4 m/s²

t = 10s

u = 0 m/s [Since the car starts from rest, the initial velocity of the car will

                   be 0 m/s]

To find:

v [Final velocity]

Applying the formula of acceleration,

$a = \frac{v - u}t$

Substituting the values into the given formula,

$4 = \frac{v - 4}{10}$

Taking the denominator, i.e., 10 to the other side,

40 = v - 4

∴ v = 40 + 4

  v = 44 m/s
