Document Summary

Phys 101: physics for the life sciences lecture 5: 2-d kinematics ii. 2 + 8] + [-15t -4] : calculate the displacement of the particle between t=2s to t=5s. R = ( xb - xa) + (yb - ya) . = (158 - 56) + (-79 - (-34)) . = 102 + (-45) : calculate the vavg between t=2s to t=5s. = 34 - 15 m/s: calculate the instantaneous velocity of the particle. r (t) = [20t + 2t. V(t) = [20 + 4t] + [-15] . 2 + 8] + [-15t -4] (take the derivative: calculate aavg between t=5s to t=10s. 5 m/s2: calculate the instantaneous acceleration of the particle. V(t) = [20 + 4t] + [-15] (take the derivative) A(t) = 4 +0 : plot an x vs y graph. A projectile was launched at some angle and is subject only to the force of gravity (neglect air resistance). The acceleration in the x-direction is zero.
