Detailed Solution

If an object starts from rest and attains an acceleration of

10 m / s^{2}

. Then the velocity of the object after

7

seconds from the start is

70 m / \sec

.
Given:
Acceleration

(a) = 10 m / s^{2}

Time

(t) = 7 \sec

By using the first equation of motion,

v = u + at

where

v

is the final velocity, and

u

is the initial velocity.

\Rightarrow v = 0 + 10 \times (7)

v = 70 m / \sec .
