A cannonball is fired from a height of 25 m above ground level, with an initial speed of 22.36 m/s and at an angle of 63.4⁰ above the horizontal. The cannonball lands at ground level. a. How long was the ball in the air (the “hang time")? b. How far does the cannonball travel horizontally? c. What is the final speed of the cannonball just before making contact with the ground?

When there is no air resistance what best describes the vectors of a projectile in motion:   a.The acceleration vector and velocity vector are both constant magnitude.   b.The acceleration vector is constant magnitude and perpendicular to the trajectory. The velocity vector is at a tangent to the trajectory   c.The acceleration vector is constant and points straight down. The velocity vector is perpendicular to the trajectory   d.The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory

A 2.00-m-tall basketball player is standing on the floor 10.0 m from the basket, as in the figure below. If he shoots the ball at a 40.0° angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket is 3.05 m. m/s 40.0 2,00 3.05 m 10.0 m

A rescue plane flies at 198km/hr and at a constant elevation of 500m toward a point directly over an accident victim struggling in the sea. The pilot must release a rescue capsule so that it hits the water very close to the victim.a). what should be the angle of the pilot’s line of sight when the capsule is released? EVb) what is the velocity of the rescue in the vertical plane when the capsule is released? APc). as the capsule reaches the water, what is its velocity ?̅in i. the unit vector notation? ANii. magnitude- angle notation

Q1. An archer aims at the bullseye of a target 50.0 m away. The arrow is at the same height as the bullseye. If the archer angles the arrow upwards at 12°, what must the arrow's initial speed be in order to hit the bullseye?

6. A projectile is launched at ground level with an initial speed of 46.0 m/s at an angle of 35.0° above the horizontal. It strikes a target above the ground 2.70 seconds later. What are the x and y distances from where the projectile was launched to where it lands? 7. A ball is thrown horizontally from the top of a 54.0-m building and lands 117.3 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) (a) How long (in s) is the ball in the air?  s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.)  m/s (c) What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.)  m/s (d) What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude…

Doha kicks the ball in a parabolic path. The ball leaves the player’s foot with a speed of 20 m/s, making an angle of 40 o with the horizontal. a) Calculate the maximum height of its trajectory  b) Determine its velocity as it hits the ground again. Air resistance is negligible. c) How far from Darshan does the soccer ball land?

6. A person kicks a soccer ball such that it leaves the ground with an initial velocity of 20.0 m/s at an angle of 18.0° above the horizontal. The ball travels 9.00 meters horizontally where it then arrives at the goal that has a height of 2.13 m. a) Assuming the goalkeeper is not able get to the ball, does it score a goal? b) If the ball has a diameter of 0.220 m, how far above or below the top of the goal is the nearest part of the ball? c) What is the velocity of the ball when it reaches the goal? Answers: (a) GOALLLLLL!!! (b) 8.27 cm below the top, (c) 19.1 m/s @ 4.64°
