Question

Assume that the apple has a mass of 0.35 kg. The raccoon throws the apple with an angle of 60 deg to the floor with an initial velocity of 4 m/s.1. Determine the maximum height that the apple will reach.
2. How long will the apple be in the air?
3. Determine the horizontal distance that the apple will travel

Answer 1

1. Determine the maximum height that the apple will reach.

$$h=\frac{v_y^2}{2g}=\frac{v^2\sin^2\theta}{2g}=0.612\text{ m}.$$

2. Find how long will the apple be in the air.

$$t=2\sqrt{\frac{2h}{g}}=0.706\text{ s}.$$

3. Determine the horizontal distance that the apple will travel

$$R=v_xt=v\cos\theta·t=1.41\text{ m}.$$
