##### A 48.0 kg child is stationary in the middle of an ice rink (no friction)
A 48.0 kg child is stationary in the middle of an ice rink (no friction). A 0.750 kg football is thrown with a velocity of 21.2 m/s moving eastward. The child catches the ball and together they slide off in the eastward direction with a velocity of 0.326 m/s.a.) Find the impulse (magnitude and direc...

##### When the thigh is fractured, the patient's leg must be kept under traction
When the thigh is fractured, the patient's leg must be kept under traction. One method of doing so is a variation on the Russell traction apparatus. (See the figure.) Please place period in place of (dot)oi53(dot)tinypic(dot)com/2a0b7yx(dot)jpgIf the physical therapist specifies that the tractio...
##### A hot air balloon is ascending straight up at a constant speed of 5.70 m/s
A hot air balloon is ascending straight up at a constant speed of 5.70 m/s. When the balloon is 11.0 m above the ground, a gun fires a pellet straight up from ground level with an initial speed of 33.0 m/s. Along the paths of the balloon and the pellet, there are two places where each of them has th...
