Question

The wrench starts at rests and is accelerating at 2 m/s^ 2 while you throw it at a given time you notice it has a velocity of 10 m/s how long was it accelerating for?

Answer 1

Given:

Acceleration = 2 m/s^2

Velocity = 10 m/s

Let's find the time(how long it was accelearating for).

To find the time, apply the formula:

`t=(v-u)/(a)`

Where:

t is the time

v is the final velocity = 10 m/s

u is the intial velocity = 0 m/s

a is the acceleration = 2 m/s^2

Thus, we have:

`\begin{gathered} t=(10-0)/(2) \\ \\ t=(10)/(2) \\ \\ t=5\text{ } \end{gathered}`

Therefore, the wrench accelerated for 5 seconds.

ANSWER:

5 seconds
