2. Force = Mass x Acceleration
Forces and Motion Problems Day 2
Force = Mass x Acceleration
1. If a bird with a mass of 2 kg is accelerating at a speed of 3 m/s/s, what is the force (in Newtons) being used by the bird?
6 Newtons
2. A snow skier with a mass of 60 kg is accelerating at a speed of 7 m/s/s, what is the force being used by the skier?
420 Newtons
3. How much force is being used to accelerate a 55 kg cart at 15 m/s/s?
825 Newtons

3. Forces and Motion Problems Day 3 Force = Mass x Acceleration F = M x A
Acceleration = Force / Mass A = F / M
Mass = Force / Acceleration M = F/A

300 kg
2. If a force of 1920 Newtons was used to accelerate you at 8 m/s/s, what (in kg) is your mass?
240 kg
3. If a kg rocket is being accelerated at 62 m/s/s, what is the force being used to accelerate it?
Newtons

4. How much would a person weigh on Earth if they had a mass of 28 kg?
Forces and Motion Problems Day 4
Weight on Earth = Mass x 9.8
Weight can be expressed in terms of Newtons
How much would a person weigh on Earth if they had a mass of 28 kg?
How much would a person weigh on Earth if they had a mass of 13 kg?
How much would a person weigh on Earth if they had a mass of .7 kg
274.4 Newtons
127.4 Newtons
6.86 Newtons

5. Momentum = Mass x Velocity
Forces and Motion Problems Day 5
Momentum = Mass x Velocity
What is the momentum on a 3 kg hammer if the velocity of the swing of it is 1.5 m/s?
What is the momentum of a .045 kg golf ball traveling at 16 m/s?
Which has more momentum, a 700 kg car traveling at 40 m/s or a 480 kg car traveling at 70 m/s?
4.5 kg-m/s
.72 kg-m/s
The 480 kg car

6. Forces and Motion Problems Day 6
1. 2 people are pushing a box in the same direction. The 1st person is using a force of 12 Newtons and the 2nd person is using a force of 7 Newtons. What is the total net force?
19 Newtons
2. Jack and Jill are pushing a cart toward each other. Jack uses a force of 8 Newtons while Jill uses a force of 8 Newtons. What is the net force being used?
0 Newtons
3. If James is pushing a crate using 28 Newtons and Jeff is also pushing the crate, but in James’s direction, using 14 Newtons, what is the net force being used?
14 Newtons
4. Which problems indicate an unbalanced force?
1 and 3

7. Force = Mass x Acceleration
Forces and Motion Problems Day 7
