The boy at A attempts to thrown aball over the roof of a barn such that it launched at an angle 8A=40°. Determine the minimum speed VA at which. must throw the ball so that it reaches it maximum height at C and the distance d where the boy must stand so that he can make the throw. jom XX +5m 20.67 m/s, 16.37 m 19.9 m/s, 15.3 m 12.72 m/s, 10.91 m

Q2: A stake is being pulled out of the ground by means of two ropes as shown. Knowing that a 5 308, determine by trigonometry (a) the magnitude of the force P so that the resultant force exerted on the stake is vertical, (b) the corresponding magnitude of the resultant 120 N 25° a

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 12 ft/sec. If the shooting guard is to catch the ball at a height of 6.1 ft at C while in full stride to execute a layup, determine the speed v0 and launch angle θ with which the point guard should throw the ball.

3. A toboggan and rider of total mass 90 kg travel down along the smooth slope defined by the equation y=0.08x². At the instant x - 10 m, the toboggan's speed is 5 m/s. At this point, determine the rate of increase in speed and the normal force which the slope exerts on the toboggan. Neglect the size of the toboggan and rider for the calculation. v=5m/s/ y=0.08.² 10 m
