(adsbygoogle = window.adsbygoogle || []).push({}); 1. A soccer ball is kicked so that it has a range of 30m and reaches a maximum height of 12m. What velocity (magnitude and direction) did the ball have as it left the footballer's foot?

I used the equation to solve for time and got 1.55s. I'm not sure if air resistance is involved, we never discussed how to solve problems with air resistance in class.

2. A stone is thrown with a speed of 20.0 m/s at an angle of 48° to the horizontal from the edge of a cliff 60.0m above the surface of the sea.

(a) Calculate the velocity with which the stone hits the sea.

(b) Discuss qualitatively the effect of air resistance on your answers to (a).

3. The maximum height reached by a projectile is 20m. The direction of the velocity 1.0s after launch is 20°; find the speed of launch.

Is air resistance included in all of these problems?
