Question

B. A bomb explodes into three identical pieces. One flies in the +y-direction at 13.4 m/s, a second in the -x-direction at 16.1 m/s. Give the x component of the velocity of the third mass in m/s.

C.In the previous problem, give the y component of the velocity of the third mass in m/s.

D.A 1070-kg car and 3420-kg truck undergo a perfectly inelastic collision. Before the collision, the car was traveling in the –y direction at 1.45 m/s, and the truck was traveling in the +x direction at 9.20 m/s. Find the velocity of the wreckage immediately after the collision. Give the x component of the velocity in m/s.

E.In the previous question, what is the y component of the velocity in m/s.

Explanation / Answer

B). M×0 = (m/3)(13.4j) + (m/3)(16.1)I +(m/3)(v)

X component of third mass = -(16.1)I in the negative x direction.

C). Y component of third mass equals = -(13.4) m/s

As per chegg policies i can solve only 1 question.
