Answer #1

•A basketball is rolling on a horizontal surface - A=0

•A basketball flies vertically up - A<0

•A basketball falls vertically down - A>0

•A basketball to thrown at angle to yhe horizon(moves on a parabolic tragectory) - sign of work is changed during the motion

    please explain III Which of the following is the correct graphical representation for C-(A-B)? (Symbols in bold type are vectors) IIII] When a ball is thrown vertically up with some initial speed it slows down as it moves up reaches a certain maximum height, and then falls straight down. Assume no air friction. During the trajectory of the ball in the air, which one of the following is true? lal The acceleration and velocity of the ball both increase on...

    Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

    1. A football has a mass of mp = 0.413 kg. It can be approximated as an ellipsoid 6 in diameter and 12 in long. A 'Hail Mary' pass is thrown upward at a 45° angle with an initial velocity of 55 mph. Air density at sea level is p= 1.22 kg/m². Neglect any spin on the ball and any lift force. Assume turbulent flow and a constant air-drag coefficient of Cp = 0.13. The equation of motion of the...
