Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at vA = 2.8 m/s , and ball B is moving to the right along the x axis with speed vB = 5.8 m/s . After the collision, assumed elastic, ball B is moving along the positive y axis(Figure 1). Part A What is the final direction of ball A? Express your answer using two significant figures. clockwise from the +y-direction
Part B What are their two speeds? Express your answers using two significant figures. Enter your answers numerically separated by a comma.

Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Ball A is moving upward along the y axis at vA = 2.7 m/s , and ball B is moving to the right along the x axis with speed vB = 5.5 m/s . After the collision, assumed elastic, ball B is moving along the positive y axis(Figure 1). Part A- What is the final direction of ball A? Part...
Two billiard balls of equal mass undergo a perfectly elastic head-on collision. If one ball's initial speed was 1.70 m/s , and the other's was 5.00 m/s in the opposite direction, what will be their speeds after the collision? Enter your answers numerically separated by a comma.
please do part a and b, thank you.
One billiard ball with a mass 1.20 is moving south with a speed of 4.00m/s. A second billiard ball with a mass of 0.80 kg is moving north with a speed of 5.00m/s. The balls have a glancing collision, which lasts for 6.0 ms. As a result of the collision, the first ball Is deflected by 90 degree, sending it east with a speed of 3.00 m/s. What is the velocity of...
Two (frictionless) billiard balls strike each at right angles. Ball one and ball two both have initial velocities of 10 cm/sec. Their mass is .15 kgs. ? What are the velocities of the balls after they collide? ? What direction are they traveling?
One billiard ball is shot east at 1.7 m/s . A second, identical billiard ball is shot west at 0.90 m/s . The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90∘ and sending it north at 1.33 m/s . 1) What is the speed of the first ball after the collision? Express your answer to two significant figures and include the appropriate units. 2) What is the direction of the first ball after...
Billiard ball A of mass mA = 0.125 kg moving with speed vA = 2.80 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg . As a result of the collision, ball A is deflected off at an angle of θ′A = 30.0∘ with a speed v′A = 2.10 m/s, and ball B moves with a speed v′B at an angle of θ′B to original direction of motion of ball A. Part C Solve these equations...
Two billiard balls, a cue ball and an eight ball, of equal mass undergo a perfectly elastic head-on collision. If the cue ball’s initial speed was 8.8 m/s, and the eight ball's was 8.3 m/s in the opposite direction, what will be the velocity of the eight ball after the collision? Consider the initial direction of the cue ball to be the positive direction.
Ch.7, 7 Two billiard balls of equal mass undergo a perfectly elastic head-on collision. Part A If one ball's initial speed was 2.50 m/s , and the other's was 4.20 m/s in the opposite direction, what will be their speeds after the collision? V1, V2?
Two billiard balls of equal mass undergo an elastic equation. Ball 2 is initially at rest and ball 1 has a speed of 12m/s. After the collision, both balls move at an angle of 37 degrees and 53'degrees, respectively, with respect to its initial direction (figl) Find the speed of each ball after the collision.
Two billiard balls of equal mass undergo a perfectly elastic head-on collision. If one ball's initial speed was 1.60 m/s , and the other's was 3.60 m/s in the opposite direction, what will be their speeds after the collision?
