Simply use the equation

v=u+at

assuming car started from rest then

initial velocity u=0

so final velocity

v = 15*2=30 m/s^2  ·

Here you can use the suvat equations.

What we know;

S (displacement)=?

U (initial velocity)=0

V (final velocity)= what we’re trying to find

A (acceleration)=15m/s2

T (time)=2seconds

We then use the formula which includes the variables that we have which is;

V=U+AT

Therefore;

V=0+(15)(2)

V=30m/s

Therefore the velocity of the car is 30m/s

Hope that helps!

As mentioned earlier in Lesson 1, an object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students... more Monti Mehta
