Ionsider the ski jump track shown in Figure 2 below. The radius of curvature of the track is r= 60 [m] and the ski jumper's mass is 65 [kg]. The ski jumper's angular displacement, 6 is defined from the horizontal as shown. The ski jumper goes along the ski jump track for 6 = 120° before launching at an angle B = 30° above the horizontal. r=60[m] 0 0=120° LAUNCH POINT ski jumper B -GROUND Figure 2: Ski jumper attempting...

A basketball star covers 2.65 m horizontally in a jump to dunk the ball. His motion through space can be modeled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.95 m above the floor and is at elevation 0.910 m when he touches down again. (a) Determine his time of flight (his "hang time" (b) Determine his...

A Chinook salmon can jump out of water with a speed of 6.70 m/s . How far horizontally ? can a Chinook salmon travel through the air if it leaves the water with an initial angle of ?=26.0° with respect to the horizontal? (Let the horizontal direction the fish travels be in the +? direction, and let the upward vertical direction be the +? direction. Neglect any effects due to air resistance.)

A helicopter is rising from rest vertially upward at 3 m/s2. At t=5 seconds, it launches a prjectile at 40 m/s at 30 degrees from the horizontal. a) depict a v/t graph of the helicopter from t=0 to t=5 b) calculate the height of the helicopter is above ground in 5 seconds. c) calculate the additional "vertical" height the projectile reaches after being launched from the helicoper. d) calculate how far horizontally the projectile would travel before striking the ground.
