- Messi is keeping his free-kick skills sharp this quarantine by playing football with his neighbour's monkey. From the roof of his house, which is 7 meters above the ground, he kicks a ball horizontally towards his neighbour's house, which is 6 meters away and also has a roof that is 7m above the ground. At the same instance, his neighbour's pet monkey drops off the ledge of his roof to try to catch the ball. Please ignore air resistance, and take g=9.81m/s2 Minimum velocity? What is the minimum speed (in m/s) at which Messi must kick the ball horizontally so that the monkey is able to catch it just before hitting the ground? Time? If Messi kicks the ball with the minimum required speed; at what time (in seconds) after the kick is the monkey able to catch the ball? Please provide your numerical answer to three significant figures; eg in the form x.xxA boy is standing from the top of a cliff 8 m from the ground and he has a bow which is aimed 40 degrees from the horizontal. He can release the bow with an initial velocity of 15 m/s. An animal is below the cliff and is moving towards the boy at a velocity of 5 m/s. For the bow to hit the animal, at what distance D should the animal be when the bow is fired?A baseball player friend of yours wants to determine his pitching speed. You have him stand on a ledge and throw the ball horizontally from an elevation 3.0 m above the ground. The ball lands 20 m away. What is his pitching speed?
- A baseball batter hits his home run ball with a velocity of 110 ft/s at an angle of 45° above the horizontal.

What is the horizontal distance between the end of the rifle and the bull's-eye?The highest barrier that a projectile can clear is 15.7 m, when the projectile is launched at an angle of 14.2° above the horizontal. What is the projectile's launch speed?

What is the minimum speed (in m/s) at which Messi must kick the ball horizontally so that the monkey is able to catch it just before hitting the ground? Please provide your numerical answer to three significant figures; eq in the form x.xxTwo friends are playing catch, indoors, with a baseball, where the ceiling height is 6.15mm. The first friend releases the ball at a height of 3.15mm with a velocity of 21.8m/sm/s, and the second friend catches it at the same height. Neglect the diameter of the baseball. What is the maximum vertical component of the velocity, in meters per second, such that the baseball does not hit the ceiling?Two friends are playing catch. They both are about the same height so the release height of the ball when thrown and the height of the catch are both 1.75 meters above the ground. The friend on the right throws the ball at a speed of 15 m/s at an angle of 33° above the horizontal. Assume you can ignore air resistance for this problem. (1) What are the horizontal and vertical components of the initial velocity of the ball? (2) How far away should the second friend stand to catch the ball (at a height of 1.75 m above the ground)? 1: You'll first need to solve for the time the ball is in the air. 2: If you don't know how to solve for time, then pick a value for the time the ball is in the air and perform your remaining calculations using that value for time
