## If we have a constant acceleration of 20 m/s2 and an initial velocity of 5 m/s, what is the velocity after 10 seconds?

Question

Velocity V(t) = V(0) + a*t = 5 + 20*10 = 205m/s at t = 10s

You have asked at least FOUR rudimentary questions. If you are struggling with your homework you need to talk to your teacher ASAP.

These questions are the simplest type of problem that can exist.

They involve KNOWING your formulae,

SELECTING the correct one and

SUBSTITUTING the values.

If you need to ask then you have failed ONE ( or more ) of these tasks and need to find out why. Urgently.

Some formulae are

s = ut + 1/2 a t^2

v = u + at

s = (u+v)/2

v^2 = u^2 + 2as

Only one of these contains the symbols for the problem as asked.

v = u + at

substitute

v = 5 + 20 * 10

calculate

v = 5 + 200 ( BODMAS rules )

= 205 m/s
