- A tall 2 meter tall basketball player shoots for the net that stands 3 meters from the ground. If he throws he ball from head height at an angle of 60 degrees and the ball travels at 10 meters per second, how far away is the hoop?
- Two cables hold a mass of 100kg, joining in the middle of the top of the mass. Two helicopters lift a cable each and hover so that the height of the mass is constant. Each cable makes an angle of 57° with the normal. Find the tension in each cable.
- Explain the difference between elastic and inelastic collisions.
- A drone is hovering at a constant height above the ground. The mass of the drone is 7 kg. The mass of the package is 3 kg. Calculate the upward force of the Drone.
