Week 6 Lesson

• Physics

Sam is attempting to pass a ball to Casey. Sam throws the ball at a 45 degree angle and Casey is 30 meters away. Given the acceleration due to gravity is 9.8 m/s^2, and air resistance is negligible, how hard must Sam throw the ball?

1. 15 m/s
2. 30 m/s
3. 23.25 m/s
4. 17.15 m/s

I want to launch a ball into a large bin that is 10 m long. The bin begins 30 m away from me and continues to 40 m away from me. If I launch the ball from ground level at a 30 degree angle such that it lands in the bin, what is the minimum initial velocity I must provide?

1. 32.3 m/s
2. 21.2 m/s
3. 18.4 m/s
4. 20.8 m/s

I throw a ball straight up. At what time is it going to reach its peak height if i throw it at 30 m/s?

1. 45.8 m
2. 30 m
3. 3 m
4. 50.4 m
