Question

A car with a velocity of 30 m/s is accelerated uniformly at the rate of 2.0 m/s2 for 10 s. What is its final velocity?

Answer 1

\[v=v_0+at\]

Answer 2

the first thing you want to do is determine the given
Vi=30m/s
A=2.0m/s2
T=10s
after that set up an equation, since you want to find the final velocity you can use the
Vf=Vi+at
plug in all the given number
Vf=30m/s+(2.0 m/s2)(10s)
so the Vf is equal to 50m/s

hope that's helpful.
