Review of Speed, Velocity, & Acceleration
WRITE ON YOUR OWN PAPER
Answer each question COMPLETELY. Some questions may have multiple parts, be sure to answer each part. When completing calculations, show ALL work (1. Write the formula 2. Show what is being substituted in the formula 3. Provide answer that includes proper SI units)
What do the following units represent? Use D for distance, T for time, S for speed, or A for acceleration.
1.___14 km 2.___ 6 hours 3.____14 mi 4.___4 m 5.___30 m/s 6.___12 m/s2
7.___2 sec 8.___6 cm 9.___34 min 10.___150 mph 11.___25 ft 12.___3 km/hr
CALCULATIONS
13. Goldie Goldfish, a speed swimmer, loves to race around the park’s pond, which is 45 centimeters around. If she can swim 10 laps around the track in 2 minutes, what is her average speed in m/s?
14. At exactly 2:00 pm, Speedy the Snail crawls onto a meter stick at the 10 cm mark. If he reaches the 65 cm mark at exactly 2:05 pm, what is his speed (m/s)?
15. Toon Train is traveling at the speed of 10 m/s at the top of a hill. Five seconds later it reaches the bottom of the hill and is moving at 30 m/s. What is the rate of acceleration of Toon Train?
16. Pete the Penguin loves to sled down his favorite hill. If he hits a speed of 50 m/s after 5 seconds, what is his rate of acceleration? Hint: He starts at 0 m/s at the top of the hill.
17. Monster Mike’s truck decelerates from 72 m/s to 0 m/s in 6 seconds. What is his rate of deceleration?
18. Starting from rest and moving in a straight line, a runner achieves a speed of 7.0 m /s in a time of 4.5 seconds. Determine the average acceleration of the runner.
19. A runner has a mass of 89 kilograms. He produces a force of 84 Newtons between the ground and his running shoes. How fast does he accelerate?
20. Calculate the acceleration of a jet car racing on the Bonneville Salt Flats if the force on it (the “Thrust”) is 500,000 Newtons and the mass is 2,100 kilograms.
21. Calculate the acceleration of a car if the force on the car is 450 Newtons and the mass is 1300 kilograms.
22. Your bicycle has a mass of 9.1 kilograms. You accelerate at a rate of 1.79 m/s2. Calculate the net force that is accelerating the bicycle.
