Bill throws a tennis ball to his dog. he throws the ball at a speed of 15 m/s at an angle of 30° to the horizontal. assume he throws the ball from ground level.
a. if bill and his dog start in the same place, how fast should his dog run to intercept the ball exactly as it lands on the ground? (1 point)
b. how fast should the dog run to get to where the ball will be at a height of 2 m as it falls back toward the ground, and to get there 0.5 seconds before the ball gets there? (hint: in this problem, you will need to consider both the x- and y-coordinates of the ball's position.) (1 point)
question 12 (4 points)
a baseball player hits a ball at a speed of 34 m/s at an angle of 30°. when the ball hits the bat, it is 1.2 m above the ground. an outfielder positions himself 98 m from where the ball was struck, and the ball flies over his head.
a. at what time does the ball pass over the outfielder's head? (1 point)
b. standing straight up, the outfielder can raise his glove to a height of 2.3 m. how high does the ball fly over the outfielder's glove? (1 point)
c. he can jump upward at a speed of 7 m/s. at what time after the ball is hit should he jump so that his glove intersects the path of the ball? (1 point)
d. why are there two possible solutions for part (c)? (1 point)
i'm sorry i know its alot but it is for my online physics class that i am trying to get a better grade in and complete my 15 assinmentz
