Question

skater n 58.9 kg is moving north at a speed of 7.8 m/s when she collides with skate E 72.6 kg moving east at 3.5 m/s the two skates together in what direction and with what speed do they move after the collision draw and label a momentum vector diagram show

Answer 1

The momentum vectors are

(0,58.9*7.8) and (72.6*3.5,0)

Their sum is

(254.1,459.42)

So, since the combined mass is 58.9+72.6=131.5

the resultant velocity vector is v=p/m

(1.93,3.49)

or 3.99 at E61°N
