X Incorrect In a basketball game, the point guard A intends to throw a pass to the shooting guard B, who is breaking toward the basket at a constant speed of 11 ft/sec. If the shooting guard is to catch the ball at a height of 7.1 ft at C while in full stride to execute a layup, determine the speed vo and launch angle with which the point guard should throw the ball. A Answers: Vo = a 0= % 0 15.6 110.6 18.26 11 ft/sec B ft/sec 22° C 7.1'
Recall that the Range equation gives the horizontal distance a projectile can be launched. Suppose there is a slight breeze so that the range equation is modified in the following way: R(0) : = sin(20) – 0.900 R Part A Use Calculus to determine the angle (in degrees) at which the projectile will reach its maximum range. ?

A block of mass 3000 g is attached to a spring whose spring constant is k = 8 N/m. The block slides on an incline with e = 37°. The block starts at rest with the spring unstretched before sliding down a distance of 60 cm down the incline. Assume that uk = 0.20. Use g = 9.8 m/s2 What is the velocity (m/s) of the block as soon as it slides 60 cm down the incline?
As part of an obstacle course, an athlete must kick a soccer ball into a 1 meter wide and 10 meter deep pit such that the ball hits a target at the bottom of the pit. In practice, a dynamics student that is participating in the race kicks the soccer ball such that the soccer ball will bounce off the far wall of the pit 5 meters below the surface and head towards the target. If the velocity of the ball before striking the wall at point at point A is v4 = 2.6i – 10j m, determine the t-component of the ) after striking the wall. The size of the ball and the target ball velocity vector (in are negligible relative to the dimensions of the pit, the gravity acceleration must be considered as g 10 m and the coefficient of restitution at point A is e =0.35. 5 m t 10 m 1m 三

A woman at an airport is rolling her suitcase (mass = 20 kg) at an initial velocity of 1 m/s by pulling on a strap at an angle of 30° above the horizontal with a force of 33 N. The woman starts to speed up when she realizes that she is late for her flight. She pulls the suitcase over a distance of 50 m as she walks to her gate. What is the speed of the suitcase when she reaches her gate? (You can neglect friction in this problem. Give your answer in m/s.)

After being hit with a white ball, the black 8 ball moved 12.78 inches at an angle of 35° N of E from its resting position. Once it strikes the side of the billiard table, it bounced off an angle of 41° W of N and traveled 30.9 inches, and after striking the side of the table again, traveled another 5.030 inches at an angle of 45° S of W before coming to a full stop. How far is the black 8 ball from its original position? H Scale: 0.5 cm = 1.0 inch
During a baseball game, a baseball is struck, at ground level, by a batter. The ball leaves the baseball bat with an initial speed v0=50.7m/s at an angle θ=40.5∘ above the horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Ignore air resistance throughout this problem. 1)Express the magnitude of the ball’s initial horizontal velocity component, v0,x, in terms of v0 and θ. 2Express the magnitude of the ball’s initial vertical velocity component, v0,y, in terms of v0 and θ. 3)Find the ball’s maximum vertical height, hmaxℎmax, in meters, above the ground. 4)Enter an expression in terms of v0, θ, and g for the time it takes the ball to travel to its maximum vertical height. 5)Calculate the horizontal distance, xmax, in meters, that the ball has traveled when it returns to ground level.
A block of mass m = 3 kg is sliding along a frictionless inclined surface that makes an angle of y = 30°with respect to the horizontal surface. At the lowest points of the inclined surface, a projectile is fired at a speed of vo = 12 m/s that makes an angle 0, = 45° with respect to the horizontal. Our aim of this problem is to find the time when the projectile will hit the block. e = 450 h = ? Ro= 10 m P = 30° x= ? (a) Find the time when the projectile hits the block.
