A telemetry system is used to quantify kinematic values of a ski jumper immediately before the jumper leaves the ramp. According to the system r=560 ft , r˙=−105 ft/s , r¨=−10 ft/s2 , θ=25° , θ˙=0.07 rad/s , θ¨=0.06 rad/s2 Determine the velocity of the skier immediately before leaving the jump.
The velocity of the skier immediately before leaving the jump along with its direction is ? I have 112.08 ft/s but can't seem to get the direction correct. Determine the acceleration of the skier at this instant.
At this instant, the acceleration of the skier along with its direction is ? acceleration is 22.8 ft/s^2 but need help with direction. Need help with velocity direction and acceleration direction please.
For Problems 18-22 (Table 7-27), design a V-belt drive.
