Velocity, Acceleration, and Force Problems: SHOW YOUR WORK. LABEL YOUR ANSWER!!!!!
35. A car is driving 130 km in 2 hours. What is the car’s velocity?
36. Calculate the acceleration (in m/sec2) of a missile that goes from 0 km/s to 8.8 km/s in 2 sec. How does this
compare to the acceleration of gravity? (about 10 m/s2)
37. A kid on a bicycle rides 12 km in 1.5 hours. What was his velocity?
38. Parker is in a grocery cart that has a mass of 35 kg and is accelerating at a rate of 2 m/s2. What is the
