Question

The initial speed of a body is 7.58 m/s. What is its speed after 2.22 s if it accelerates uniformly at 3.62 m/s 2 ? Answer in units of m/s.

Answer 1

Answer:

Final speed of the body, v= 15.61 m/s

Explanation:

It is given that,

Initial speed of a body, u = 7.58 m/s

Uniform acceleration, $a=3.62\ m/s^2$

Time, t = 2.22 s

We need to find the speed of the body after this time. The first equation of motion is as follows :

$v=u+at$

$v=7.58+3.62\times 2.22$

v = 15.61 m/s

So, the speed of the body after 2.22 seconds is 15.61 m/s. Hence, this is the required solution.
