4. On a day with heavy rainfall, when the roads were slippery, the two cars, A and B, collided at right angles at the intersection. During the collision, the cars became entangled (AB) and moved off together to bump to a huge old tree. Calculate the velocity (km/h) of car B just before collision with car A at the intersection. Right after bumping with the tree, determine the new velocity of the "entangled" cars. Also, compute for the percent energy lost from the cars after the two collisions occurred. Neglect the geometry of the cars before and after collision. Other details are tabulated below: Parameter Mass of car A, m₁ (kg) Mass of car B, mB (kg) Velocity of car A just before collision with car B, VA1 (km/h) Velocity of car B just before collision with car A, VB1 (km/h) Coefficient of restitution between cars A and B, CAB Coefficient of restitution between the entangled cars (AB) and the tree (C), eABC Value (with respect to your student number) 1290 1630 55, 1 unknown, → unknown…
Problem 21.1 The lunar module is designed to make a safe landing on the moon if its vertical velocity at impact is Vmax ≤ 5 m/s. The acceleration of gravity on the moon is 1/6 the value on earth, gmoon = gearth/6.
