- A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 28.5 m/s. A net is positioned a horizontal distance of 52.5 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil? mFort Gaines guards the western entrance to Mobile Bay. In order to prevent enemy ships from passing, it needs to be able to cover about 1 km of the bay with cannon fire. The cannons fire projectiles horizontally at a speed of 460 m/s. How high must the cannons be located above the ground in order for their projectiles to travel 1 km horizontally?A projectile is thrown from the top of a tall building with a height of 74.4 m with an initial velocity of 24.7 ms in the horizontal direction. What will be the magnitude of the angle, in degrees, of the projectile’s velocity with respect to the +x-axis immediately before striking the ground? Round your final answer to 1 decimal place for the angle in degrees.
- A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 24.0 m/s. A net is positioned a horizontal distance of 49.5 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?A parent at a Little League game returns a foul ball by throwing it back onto the field. When the parent throws the ball back, she is standing and ends up releasing the ball from a point that is 2.50m above the ground. Your best guess is that she threw the ball upward at an angle of 60o with respect to the ground and it landed 13m away from her. What was the height of the ball's apex (as measured from the ground)?Some cats can be trained to jump from one location to another and perform other tricks. Kit the cat is going to jump through a hoop. He begins on a wicker cabinet at a height of 1.722 m above the floor and jumps through the center of a vertical hoop, reaching a peak height 3.130 m above the floor. (Assume the center of the hoop is at the peak height of the jump. Assume that +xaxis is in the direction of the hoop from the cabinet and +y axis is up. Assume g = 9.81 m/s2.) (a) With what initial velocity did Kit leave the cabinet if the hoop is at a horizontal distance of 1.550 m from the cabinet? (Express your answer in vector form. Give your answer to at least two decimal places for each vector component.) v0 =?m/s (b) If Kit lands on a bed at a horizontal distance of 3.580 m from the cabinet, how high above the ground is the bed?In m
- A playground is on the flat roof of a city school, h, - 6.30 m above the street below (see figure). The vertical wall of the building is h= 7.50 m high, to form a 1.2-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of e = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. m/s (b) Find the vertical distance by which the ball clears the wall. (c) Find the horizontal distance from the wall to the point on the roof where the ball lands.When the red kangaroo of Australia is moving at full speed, it can bounce at a speed of 8.50 meters per second, at an angle of 45.0o above horizontal. Assuming the kangaroo is bouncing on level ground, how far will the kangaroo travel in a single bounce?A playground is on the flat roof of a city school, hb = 6.40 m above the street below (see figure). The vertical wall of the building is h = 7.70 m high, to form a 1.3-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of ? = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall.
