A cannonball is shot from ground level with an initial speed of 75.0 m/s. If the maximum height reached by the ball is 25 m, calculate: a) the angle at which the ball left the cannon with respect to the horizontal, b) how far from the cannon the ball landed, c) the time of flight of the ball

Ball is thrown from the rooftop with an initial down with velocity of magnitude va= 1.1 m/s. The rooftop is a distance above the ground, h= 36m. In this problem use a coordinate system in which upwards is positive. Find the vertical component of the velocity vfy, in meters per second with which the ball hits the ground. If you wanted the balls final speech to be exactly 27.3 m/s, from the heigh hnew (in meters), would we need to throw it with the same initial velocity? if the height is fixed at 36 m, but we wanted the balls final speed to be 32.7 m/s, what would the vertical component of the i goal velocity viy need to be, in meters per second?

A ball is thrown upward from the top of a 24 m tall building. The ball’s initial speed is12 m/s. At the instant, a person is running on the ground at a distance of 31 m fromthe building. What must be the average speed of the person if he is to catch the ballat the bottom of the building?

A ball is thrown vertically upwards with a velocity of 20 m / s. Calculate: a) What distance does it travel at 2 seconds and what magnitude of speed does it take at 2 seconds?b) What is the maximum height?c) How long does it last in the air?

A ball was kicked at an angle of 60 degrees with respect to the floor and after 3.2 seconds landed 10 meters ahead. Calculate the average velocity in x (vx), the initial velocity in y (viy), the initial velocity (vi), and the maximum height (ymax)

42) A man wants to cross a SOD m wide. His rowing speed (relative to river 3000 m/h. The river flows with a of the water ) is the man's ualking peed Aowing & walking) he should take to get the point disctly opposite his star ting point in the shortest time ? b). How long does it take?" speed on shore is 5000 m/h. a). find the path (combined 2000 m/h. If

reverse the order of the twolegs of the walk; show that you get the same final result. Thatis, you first walk leg B , which is 20.0 m in a direction exactly40º south of west, and then leg A , which is 12.0 m in adirection exactly 20º west of north. (This problem shows thatA + B = B + A .)

A ball is thrown from an initial height of 4 feet with an initial upward velocity of 29 fus. The ball's height h (in feet) after t seconds is given by the following. h-4+291-167 Find all values of t for which the ball's height is 16 feet. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.) initial height ground - seconds O-O

1) What is the displacement of an object dropped from a height after 1.50 seconds? 2) How long will it take a dropped object to reach the ground if dropped from a height of 1.75 meters? 3) An object is flipped upward at a velocity of 30.0 m/s. At what point in its ascent will its velocity be 2.0 m/s? 4) How long will a coin launched upward at a velocity of 25.0 m/s attain a velocity of 15.0 m/s? 5) A 5-kg rock is dropped from a height of 15.0 m. a) What will be its velocity 0.75 seconds after its drop? b) What will be its velocity at a point 8.0 m from the ground? 6) How high will an object launched upward travel if its initial velocity was 15.0 m/s?

A rock is thrown out from the top of a 10 m tall building. The initial velocity and angle of the rock are 3 ?/? and 20° below horizontal.(a) What are the horzontal and vertical components of the rock’s initial velocity?(b) How long does it take the rock to hit the ground? (c) What is the horizontal distance, ?, traveled by the rock?
