A bus is traveling on I-35 at 55km/hr going South, and then changes direction and starts traveling South-
West staying at 55km/hr. What happens to its speed and velocity?

If we added pennies to the cars we sent down the ramp, what are we now testing?

You are running 200 meters around the track. AT which point will you be accelerating?
A rocket booster applies 20,000 N of force to a 2000 kg rocket causing it to accelerate to 20.0m/s 2.
15 minutes later, the rocket booster is relased and it falls through the atmosphere. The mass of the rocket is now 840.0 kg and its speed is 6.0m/s2. How much force is being applied to the rocket? Record you answer in the grid.
840. Kg
Moving at 6.0 m/s2

It takes a 20N force to cause a 0.4 kg ball to begin moving. What is the acceleration? Record your answer in the grid
