Accelerated Motion.
1. Take a look at the motion graph in Figure 1.
a) Calculate the acceleration in section A.
b) Calculate the total distance covered in the time shown (60 s).
Figure 1: Motion.
2. Susan flies in a jet going with 30 m/s at t = 0. At that time she starts to accelerate with a constant acceleration of 2 m/s2. Calculate the total distance covered after 10 minutes.
3. Susan is at rest at t = 0. At that time she starts to accelerate with a constant acceleration of 1.5 m/s2. Calculate the total distance covered after 10 minutes.
4. Susan starts at 30 m/s accelerating with -1 m/s2. Calculate the times it takes before she comes to rest.
5. Susan kicks a dog with a mass of 4 kg, using a force of 100 N. Calculate the acceleration of the dog.
6. A cat with a mass of 3 kg falls from a height of 10 m.
a) Calculate the gravitational force acting on the cat.
b) Calculate how long it takes for the cat to reach the ground.
c) How fast is the cat at t = 0.5 s?
7. Susan falls from a height of 20 m.
a) Calculate how long it takes for Susan to reach the ground.
b) How fast is the Susan at t = 0.5 s?
