A ball rolls horizontally off the edge of a tabletop that is 1.40 m high. It strikes the floor at a point 1.32 m horizontally away from the table edge. (Neglect air resistance.) (a) How long was the ball in the air? (b) What was its speed at the Instant it left the table? m/s Submit oncuor

Y 0 H D A soccer player kicks the ball, which moves as shown in the figure. You are given this information: the angle e and the maximum height H. Calculate the initial speed vo and the horizontal distance D. DATA 0 = angle = 25 degrees; H = 4.4 m; {initial speed} (in m/s) X A: 4.61 OB: 5.76 OC: 7.20 OD: 9.01 OE: 11.26 OF: 14.07 OG: 17.59 OH: 21.99 {horizontal distance) (in m) OA: 33.40 B: 37.74 OC: 42.65 OD: 48.19 OE: 54.46 OF: 61.54 OG: 69.54 OH: 78.58

3. The ball is kicked from point A with the initial velocity v 20 m/s. Determine the range P

The same projectile experiment was conducted as you did in class. A racquet ball rolls down a track, leaves the track at an initial height of 0.961m above floor, with an exit speed Vexit 1.40m/s at an angle exit 7.46°. The landing spot was repeatedly measured for ten times, and the racquet ball's horizontal range data is provided below. Data run = Landing spot (m) 1 2 0.585 0.590 3 4 0.595 0.590 5 6 0.585 0.580 7 0.580 8 = 9 10 0.585 0.580 0.575

A golfer is attempting to reach the elevated green by hitting his ball under a low-hanging branch in one tree A, but over the top of a second tree B. If the launch speed of the golf ball is vo= 114 mi/hr, what launch angle will put the first impact point of the ball closest to the pin? How far from the pin (distance d) is this impact point? VO Answers: e= 12 yd d = i i A 17' 66 yd B www 0 yd 55' 23¹ 76 yd '12 '12 yd yd

A 4 kg ball is thrown from 6 m tall building (point A) at initial vilocity 28 m/s. As shown in the figure, the ball settled at point B on top of another building with a height of 15 m above the ground . Ignoring air resistance, what is the velocity of the ball just before it strikes the top bf the other building at point B? h2- 36.6 m/s O 33.6 m/s O 24.6 m/s O 18.6 m/s O 196 m/s

A target lies a distance R = 1100 m from a cannon across level ground, and a distance d = 780 m behind a wall h = 400 m tall.  If the cannon shoots projectiles with speed 160 m/s, at what angle should the cannon fire so as to hit the target over the wall?

During WWI, the Germans had a gun called Big Bertha that was used to shell Paris. The initial velocity of the shell was 1700 m/s at an angle of 55° above the horizontal. Assume it returns to the same height as released. Ignore air resistance. 1. Find the total time in the air for the shell. 2. How far away did the shell hit? 3. Find the shell's velocity at the apex. 4. Find the horizontal and vertical velocity components just when the shell strikes the ground.
