Asnowmobile has an initial velocity of 3.0 m/s. if it accelerates at the rate of 0.50 m/s squared for 7.0 seconds, what will its final velocity be?

6.5m/s

Explanation:

Acceleration is defined as the change in velocity of a body in a specific time interval. Mathematically,

Acceleration = Change in velocity/time where;

Change in velocity = final velocity (v) - initial velocity (u)

Acceleration (a)= final velocity (v) - initial velocity (u)/time (t)

a = v-u/t

Given a = 0.50m/s²

u = 3.0m/s

v = ?

t = 7.0secs

Substituting the given datas i n the formula for acceleration gives;

0.50 = v-3/7

0.5 × 7 = v-3

3.5 = v-3

v = 3.5+3

v = 6.5m/s

Therefore the final velocity of the snowmobile will be 6.5m/s

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

it has to be b, about 97 percent.
