#2 **Projectile Launched at Angles** (from Hecht textbook) *Do your work on separate paper.*1. A silver dollar is thrown downward at an angle of 60.0° below the horizontal from a bridge 50.0 m above a river. If its initial speed is 40.0 m/s, where and at what speed will it strike the water? Ignore the effects of the air. (50.8 m/s)2. A baseball is hit as it comes in, 1.30 m over the plate. The blast sends it off at an angle of 30.0° above the horizontal with a speed of 45.0 m/s. The outfield fence is 100.0 m away and 11.3 m high. Ignoring aerodynamic effects, will the ball clear the fence? (25.5 m vertical displacement - it clears the fence)

Given:θ=30°, v=45m/s, t=1.3m 2) The range of the given projectile motion of the baseball is :…

2. Abaseball is hit as it comes in, 1.30 m over the plate. The blast sends it off at an angle of 30.0° above the horizontal with a speed of 45.0 m/s. The outfield fence is 100.0 m away and 11.3 m high. Ignoring aefodynamic effects, will the ball clear the fence? (25.5m vertical displacement - it clears the fence)
