A boy 11.5 m above the ground in a tree house throws a ball for his dog, who is standing right below the reee house and starts running the instant the ball is thrown. The boy throws the ball horizontally at 8.50 m/a.
A.) how fast must the dog run too catch the ball just as it reaches the ground? Express the answer in meters per second. (V= blank m/s)
b.) how far from the tree will the dog catch the ball? (D= blank meters)
I only need answer for letter D :)

- A basketball player is standing on the floor 10.0 m from the basket as in Figure P3.47. The height of the basket is 3.05 m, and he shoots the ball at a 40.0 angle with the horizontal from a height of 2.00 m. (a) What is the acceleration of the basketball at the highest point in its trajectory? (b) At what speed must the player throw the basketball so that the ball goes through the hoop without striking the backboard?arrow_forwardA golfer hits his approach shot at an angle of 50.0, giving the ball an initial speed of 38.2 m/s (Fig. P4.60). The ball lands on the elevated green, 5.50 m above the initial position near the hole, and stops immediately. a. How much time passed while the ball was in the air? b. How far did the ball travel horizontally before landing? c. What was the peak height reached by the ball?
