Is there a picture for this question or options ?
There is no picture or diameter/radius measurements, therefore this question cannot be answered properly.
The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
6+5=11
or
6+5=?
It shows we originally have 6 and now have 5 more having a total of 11
