Document Summary

Phys 101: physics for the life sciences lecture 6: 2-d kinematics iii. There is projectile launcher set up at the top of the cliff. The launch angle is fixed at some angle . The height of the cliff is 8 m. the launcher can launch the projectile at a certain known speed vpi . The runner is running at a known constant speed of vr . At t=0 the runner is a distance of a known value xri from the base of the cliff. At what time should you pull the trigger so that the projectile hits the ground where the runner is. Y p=0 8= 8: calculate how long the projectile is in flight ( t p. 2 g (use quadratic formula to solve for t ( v yp) . = t p ( t p is now a known quantity: calculate where the projectile lands (range).
