An Olympic diver is on a diving platform 9.40 m above the water. To start her dive, she runs off of the platform with a speed of 1.18 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/s

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 canon ball was launched with a muzzled speed of 234m/s with an angle of 16.7° from the horizontal. What is the horizontal speed of the canon ball after 2.01s?

A baseball is thrown toward a player with an initial speed of 36.6 m/s at 50⁰ with the horizontal. At the moment the ball is thrown, the player is 150 m from the thrower. At what average speed must he run toward the thrower to catch the baseball 0.914 m above the height at which it was released?

A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?

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

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.

On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 2.30 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 48.4 m/s at an angle of 32.7 ° above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball?
