Question

I have worked on these three problems for hours, help is needed badly on all three! Please provide answers for all three, I will rate. Thank you so much!!

AP8.10.1 Two equal-mass balls with speeds 10 m/s and 8 m/s collide head-on, as (5.00) shown, and bounce off each other along the original line of motion. The speeds of the balls after the collision could possibly be (not necessarily in the same order) 11 m/s and 9 m/s 9 m/s and 9 m/s 11 m/s and 8 m/s 9 m/s and 7 m/s 11 m/s and 7 m/s (0/2 submissions used) 0 9 O 1 Save AP8.10.1 Submit AP8.10.1 Section 14: Physics at play: elastic collisions and sports P8.14.1 In a one-dimensional elastic collision a ball of mass 0.61 kg, moving with (5.00) velocity 5.8 m/s, strikes an initially stationary ball of mass 0.86 kg. Find the final velocity of the initially moving ball (1/5 submissions used) m/s Save P8.14.1 Submit P8.14.1 Section 18: Inelastic collisions 8.18.2 During a snowball fight, two snowballs traveng towards each other collide (5.00) head-on. The first is moving east at a speed of 16.0 m/s and has a mass of 0.450 kg. The second is moving west at 13.5 m/s. When the snowballs collide they stick together and travel west at 3.50 meters per second. What is the mass of the second snowball? (0/5 submissions used) kg Save 8.18.2 Submit 8.18.2

Explanation / Answer

P 10.1

Using conservation of momentum

m (10) + m (-8) = m v1 + m v2

v1 + v2 = 2

hence the difference in speeds must be 2

so 11,9

or 9,7
