Question

In a historical movie, two knights on horseback start fromrest 62 m apart and ride directly towardeach other to do battle. Sir George's accleration has a magnitudeof 0.19 m/s2, while SirAlfred's has a magnitude of 0.29m/s2. How far from Sir George's starting point do theknights collide? I'm not understanding how to start the problem. Im not surewhether to use a accleration or displacement formula.

Explanation / Answer

a(g) = +0.19 m/s2a(a) = +0.29 m/s2 --------------------- x = 0*t + 0.19 * 0.5t2 ---- (1)62m- x = 0t + 0.29 * 0.5t2 ----(2)--------------------- (1) t2 = x/0.095     use in (2) 62 - x = 0.135 (x/0.095) = 1.42x 62 - x = 1.42x 62 = 1.42x+x = 2.42x 62/2.42 = x x = 25.62 meters
