Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied physical principles shown on the last page. Assuming the vehicles stick together after the collision find their combined velocity. m1 v1 y n v2 after before m2 x. The initial momentum components are: pox = m1v1 and poy = m2v 2. The final momentum components are: pox = (m1 + m2)v cos" and pox = (m1 + m2)v sin". According to the law of conservation of linear momentum the components must match, 2)v cos" # v cos" = and m v. Plugging in the numbers, " = arctan m. Substituting back in, v cos" = m v. # v = 34. 6km / h : the basketball player shown at the right wants to get the basketball spinning at 200rpm from rest in 3. 00s.
