6. A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog jumps as long as 2.2 meters have been recorded. If a frog jumps 2.2 meters and the launch angle is 45, find (a) the frog's launch speed and (b) the time the frog spends in the air. Answer - initial speed of frog = 4.6 m/s lemon off banc This is a tricky one! Use VA as the initial speed. Then you can write VAX= VA (cos 45) and VAy=VA (sin 45) Then use Ay= Vay t + 1/2 ay t2 and AX= VAX t + 1/2 axt2 (go from the beginning point of the jump to the ending point of the jump) You will then have 2 equations with 2 unknowns (each equation will have VA and t) 90.05 16 gu ball sactuals no gnbest at sold off
