If he is standing 75 from the house and throws the ball at an angle of 45 degrees, ET s, i 10.58 m/s 2.2ur - a) what speed does he need to throw the ball. b) How long does it take for the ball to fly. balliv rrrrt. 12inch meter = 16.76mo d) If he runs 10 ft/s and throws the ball where...
A man stands at the edge of a cliff and throws a rock horizontally over the edge with a speed of v0 = 15.5 m/s. The rock leaves his hand at a height of h = 46.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the rock leaves the hand m How long...

How FAR from the base of the cliff will the baseball hit the ground? C.) Upon impact, how FAST was the baseball going? D.) At what ANGLE (relative to the horizontal) did the baseball impact the ground?
O student stands at the edge of a cliff and throws a stone horizontally over the edg with a speed of 18.0 m/s. The cliff is 50.0 m above a flat, horizontal beach as shown in the figure below. How far from the base of the cliff (x) does the ball hit the beach? (Neglect air resistance) 18 m/s h 50 m to A) 57.5 m B) 184 m C) 5.64 m D) 2.77 m E) 3.19 nm

6. You throw a ball out of a window at 4 m/s at a downward 30° angle. As a result, it takes 1.5 seconds for the ball to hit the ground. 30 A. How far does this ball travel horizontally before hitting the ground? (5.2 m) B. How high is this window from the ground? C. What is the velocity of this ball just before it hits the ground? Report your answer using components, or calculate the magnitude and direction.
A cannon fires a ball horizontally with a velocity of 240 m/s. If the cannon is in a 44 meter tall tower and the ground below is flat, then (a) How long does the ball take to hit the ground after being fired?
