A car travelled 30m in 2 seconds. What was the average speed?
S=D/T, 30m/2s=15m/s
A car goes from rest to 70km/h in 4.3 seconds. What was the average acceleration?
(70km/h-0km/h)/4.3s=16.28km/h/s
If an object has a mass of 100kg and an acceleration of 15m/s/s. What is the force?
100kg*15m/s/s=1500N
What is the weight in Newtons of a person with a mass of 67.2kg on Earth?
Earth's acceleration due to gravity is 9.81m/s2
659.23N
What is the momentum of an object with a mass of 15kg and a velocity of 2m/s south?
30kg*m/s
A boy was running at 11m/s for 4 seconds. How far did he go?
Distance=Speed*Time 11m/s*4s=44m
A car goes from 52km/h to 22 km/h in 7 seconds. What was the average acceleration?
(22km/h-52km/h)/7=-4.29km/h/s
An object produces a force of 2441N. The object has an acceleration of 10m/s/s, what is the mass?
244.1kg
If you step on the scale and weigh 55kg on Earth, what is your mass?
55kg. Mass is calculated with Earth's gravity as a baseline. Scales are therefore calibrated as such.
What is the momentum of an object with a mass of 14.2kg and a velocity of 3.3m/s north?
46.86kg*m/s
A racecar did a lap on a 1000m track. The car was clocked going 110m/s. How long did it take the car to take a lap?
Time=Distance/Speed 1000m/110m/s=9.09s
A car goes from 44.22 m/s to 96.91 m/s in 5.3 seconds. What is the acceleration?
9.94m/s/s
(96.91m/s-44.22m/s)/5.3s=9.94m/s/s
An object produces a force of 600N with a mass of 12kg. What is the acceleration?
50m/s/s

Jack ran 41.21m/s. (272m/6.6s)
Jack was faster
A car had an acceleration of 9m/s and an initial velocity of 1m/s. What is the final velocity after 6 seconds?
55m/s
(Acceleration*Time)+Vi
