A blue billiard ball (2kg) with initial speed 6m/s Collides with another red billiard ball (3kg) moving in the same positive x-axis. After the collision, the first ball bounces off with speed √4m/s in a direction that makes an angle +30 with the original direction. The second ball bounces in a direction that makes an angle θ2 on the other side of the first ball’s original direction. Neglect friction. Use the x-y coordinate system shown.

(a) what’s the value of θ2?

(b) determine by mathematical whether the collision was elastic or inelastic

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

d.7.5cm is your answer

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
