Hey Ben, alright first you have to determine the acceleration of the system. Let m1=2.1kg and m2=4.9kg Use F=ma m2g-m1g=m2a+m1a (m2-m1)g=(m2+m1)a a= (m2-m1)(g)/(m2+m1) = (4.9-2.1)(9.8)/ (4.9+2.1) =3.92 ms^-2 Now we must determine the speed of m1 we use v^...

"so add 1.6m to max height 0.32+1.60=1.92m" Sorry I meant max height is = 0.32+1.60=1.92m
