PROBLEM: In a basketball tournament, a tall player shoots the ball so that it leaves his hands at an initial speed of 35.0m/s and with an estimated an angle of 50.1o.  Neglect the height of the basketball player,  a. Determine the location of the ball and its velocity (magnitude and direction) at t = 2.00s. b. Determine the time when the ball reaches the highest point of its path and its vertical distance at that time. c. Determine the range from initial point to its final position.

Assume that v, and v, are in m/s and t is in seconds. Do not include units in your answers.) m/s Vx %D m/s V. II

Joe picks up a piece of rock and throws it horizontally from a height of 2.30 m at 3.45 m/s a. how much time does the rock take to hit the ground b. what is the vertical speed of the rock as it hits the ground c how far does the rock get horizontally  d what is the rock's total velocity ( magnitude and direction) as it hits the ground?

Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)What is her speed with respect to the starting point on the bank? b.)How long does it take her to cross the river?

I throw a ball to my dog at h = 1.8 m above the ground, with initial velocity v0 = 10.25 m/s at an angle θ = 31° above horizontal. Assume the ballencounters no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position.a. My dog jumps up in the air and catches the ball at the same height that Ithrew it. Create an expression for the time, tf, the ball is in the air in terms of v0, θ, g, and h. b. Calculate the horizontal distance, d in meters, between me and my dog

A basketball player shoots a free-throw with initial velocity v0 = 8.5 m/s at an angle θ = 18° above the horizontal. Use a Cartesian coordinate system with the origin located at the position the ball was released, with the ball’s horizontal velocity in the positive x direction and vertical component in the positive y-direction. Assume the basketball encounters no air resistance.   a).  What is the maximum vertical height hmax, in meters, the ball attains above the release point.  b). Determine the time, t in seconds, the basketball takes to reach its maximum vertical height.
