A golfer hits a ball out of a sand trap onto the green. The green is 1m higher than the sand trap. The initial velocity of the ball immediately after it is hit is 8 m/s, directed 60° above horizontal. How far will the ball have traveled in the x-direction when it first hits the green? Vo = 8 m/s 60° ↑ 1m ↓ Ax = ?

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v 20.5 m/s. The cliff is h = 26.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? Xo = m Yo- m (b) What are the components of the initial velocity? m/s m/s Vox= Voy in seconds. Do not include units in your

A person looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 3.36 m/s relative to the ground. When the train moves at a constant velocity, the raindrops make an angle of 25° when they move past the window, as the drawing shows. How fast is the train moving? Number i Units HOM 25

A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away.  Find the time it takes for the ball to travel the horizontal distance to the plate.    2.5 s   0.40 s   4.6 s   0.22 s

Suppose a soccer player kicks the ball from a distance 26 m toward the goal. Find the initial speed of the ball if it just passes over the goal, 2.4 m above the ground, given the initial direction to be 36° above the horizontal. m/s

Problem 2: An object is thrown off the top of a 38-m tall building with a velocity of 350 m/s at an angle of 8.2° with respect to the horizontal. Part (a) How long is the object in the air in seconds? Numeric : A numeric value is expected and not an expression. t = Part (b) What is the maximum height the object reaches above the ground in meters? Numeric : A numeric value is expected and not an expression. hmax = Part (c) What is the horizontal distance the object covers in meters? Numeric : A numeric value is expected and not an expression. Ax =.

A hockey puck slides off the edge of a table with an initial velocity of 23.6 m/s and experiences no air resistance. The height of the tabletop above the ground is 2.00 m. What is the angle below the horizontal of the velocity of the puck just before it hits the ground? A) 72.6° B) 31.8° C 14.9° (D) 77.2° E 22.8°

A puma (aka cougar or mountain lion) is one of the best jumpers among all animals. It can jump to a height of 12.0 feet high when it leaves the ground at an initial angle of 45°. What is the initial speed (in m/s) of the puma as it leaves the ground?

Chinook salmon can cover more distance in less time by periodically making jumps out of the water. Suppose a salmon swimming in still water jumps out of the water with velocity 6.03 m/s at 40.6° above the horizontal, re-enters the water a distance L upstream, and then swims the same distance L underwater in a straight, horizontal line with velocity 2.92 m/s before jumping out again. Where L=3.67 m; t1= 0.801 sec this is a time when fish are over the water; t2= 1.256 sec; Ttotal =2.057 sec; the average horizontal velocity is 3.57 m/s. Consider the interval of time necessary to travel 2L. How is this reduced by the combination of jumping and swimming compared with just swimming at the constant speed of 2.92 m/s? Express the reduction as a percentage.

Several people stand on a bridge over a river.  The bridge is not level, so the people are all different heights above the river.  Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the speed of this stone (in m/s) just before it strikes the river?
