Immediately after the collision, the incoming ball bounces backward with a speed of 3.2 m/s. ▼ Part A Calculate the velocity of the target ball after the collision. Express your answer to two significant figures and include the appropriate units. = μᾶ Part B Value Units Submit Request Answer ? Calculate the mass of the target ball. Express your answer to two significant figures and include the appropriate units.m2 m h=7.0m ☐ Figure 1: Diagram for Problem 15 15) During a test investigation, a 40-gram bullet is fired towards a stationary block of 1.0-kg mass causing a perfectly in-elastic collision. After the collision, the block-bullet system slides up a smooth ramp, eventually coming to rest at an elevation of 7.0 meters. Calculate the speed of the bullet. Must show all steps including the equations being used.A 12 kg block, initially moving to the right, collides with a stationary 18 kg block, causing the 18 kg to move off to the right. The collision is perfectly elastic. We may conclude that after the collision, the 12 kg block will stop. move to the right with less speed than it had before the collision. move to the right with the same speed that it had before the collision. move to the left with less speed than it had before the collision. move to the left with the same speed that it had before the collision.
