airplane diving at 36.90° with the horizontal drops a bag of sand from an altitude of 0.800 km. The bag is observed the strike the ground 7.00 s after its release. What is the initial velocity of the bag (a) relative to the airplane and (b) relative to the ground?

A projectile is launched from the roof of a 10 m high building. The projectile is launched with initial velocity %0 = 60 m/s and a shooting angle with respect to the horizontal 0 = 50° Find: a) The maximum height of the projectile. b) The time it takes for the projectile to reach the maximum height. c) The horizontal distance between the base of the building and the point where the projectile hits the ground. d) The time elapsed between when the projectile is fired and when it hits the ground.

A small metal ball is fired down from the edge of a lab table at an angle of 0 = 40° below the horizontal. What are the initial x and y components of the velocity of the ball if the muzzle velocity of the cannon from which it was launched is 4 ? %3D m |

Two carts have velocities vand v, respectively. At t = 0 the distance between the two carts were zero. A passenger in cart A wants to throw a ball to cart B. The ball's initial speed with respect to cart A is vo. (a) What angle should the projectile have to reach cart 2? (b) What will be the projectile's speed at maximum height with respect to cart A, cart B, and the ground respectively? A UA B VB

(a) From a balcony a child fires a toy arrow down to the ground below. The arrow has initial speed 12 m/s and is aimed at an angle of 30° below the horizontal. The arrow takes 1.2 seconds to hit the ground. (i) Calculate the initial horizontal (✰) and vertical (ŷ) velocity components of the arrow. (ii) Calculate the height of the balcony. (b) A projectile is launched with an initial speed of 75 m/s at an angle of 52° above the horizontal. If it lands at the same height from which it was launched, calculate how long the projectile remains in the air.

A person on a cliff throws a ball with an initial velocity of 30.4 m/s at an angle of 51.40 above the horizontal. If the initial height of the ball, compared to it impact location is, Y = 17.4 m, what is the maximum height it obtains, and where does it land? (find both as measured from the base of the cliff)

1. Vivian is practicing her shooting accuracy with her slingshot by trying to shoot rubber balls into a bucket on the ground. For one particular shot for which the ball lands in the bucket, she fired her slingshot horizontally with an initial speed of 56.0 m/s at a height of 170 cm above the ground. (a) How far away is Vivian standing from the bucket? (b) What are the magnitude and direction of the ball's velocity when it lands in the bucket? Note: Please be mindful of significant figures. Also, you can assume that when the balls land in the bucket, they are on the ground.

An inflatable life raft is released from an airplane at 300 m altitude, in level flight, with an air speed of 40 m/s in the horizontal direction. At what horizontal distance from the release point does the raft strike the water?

In a game of basketball, a forward makes a bounce pass to the center. The ballis thrown with an initial speed of 5.4 m/s at an angle of 20 degrees below the horizontal.It is released 0.90 m above the floor. Calculate the horizontal distance traveled by the ball before bouncing.
