Now it's up to you to follow the process and get an answer.
- Identify the variables that you are given.
- Identify what you are being asked for.
- Choose the appropriate equation.
- Plug in and solve for the answer.
1. A car starting from rest,
gets up to 20 m/s in 5
seconds. What was its
2. What is the final velocity of
a horse that starts at 4 m/s and
accelerates at 1 m/s for 3
3. A sprinter, starting from
rest, accelerates at 2 m/s for
3 seconds. How far did he go?
4. How long would it take a
rocket to go from 100 m/s to
200 m/s, if it accelerated at
5 m/s ?
5. A jogger covers 20 m in 5
seconds, with an acceleration
of 2 m/s . What was her
initial velocity?
Make up two of your own problems - one that uses the first equation and one that uses the
- Identify the variables and the one to be solved for.
- Then set up the equation, but do not solve.
