1. A ball is kicked at an initial velocity of 66 m/s. If it takes 7.2 seconds to land, what angle was it kicked at? Use -10 m/ss for acceleration. Leave no spaces between answer and units. Leave the answer to zero decimal places

2. A ball is kicked at an initial velocity of 49 m/s. If it takes 2.8 seconds to reach the apex, what angle was it kicked at? Use -10 m/ss for acceleration. Leave answer to zero decimal places.

3. A ball is kicked with an initial velocity of 58 m/s. If the ball's maximum height reached is 50 m, what was the angle of projection? Use -10 m/ss for acceleration. Leave answer to zero decimal places.

4. If a ball has a maximum displament of 68 and a maximum height of 62, what was its initial velocity? Use -10 m/ss for acceleration. Leave the answer to zero decimal places

5. If a ball has a maximum displament of 299 and a maximum height of 189, what was its initial angle of release. Use -10 m/ss for acceleration. Leave the answer to zero decimal places.
