Ball B, moving in the positive direction of an x axis at speed v, collides with stationary ball A at the origin. A and B have different masses. After the collision, B moves in the negative direction of the y axis at speed v/5. In what direction does A move, as an angle with respect to the x axis?
A car moving with an initial speed v collides with a second stationary car that is one-half as massive. After the collision the first car moves in the same direction as before with a speed v/3. (a) Find the final speed of the second car. (b) Is this collision elastic or inelastic?
y A 2 kg ball moving to the right along the x-axis at 5.0 m/s collides with a stationary 4.0 kg ball After the collision, the 2 kg ball is seen moving at 370 above the x-axis and the 4 kg ball is moving at 60° below the x-axis as shown below in the diagram. a) Find the speed of the each ball after the collision. b) Is this collision elastic or inelastic? Explain your answer with appropriate computations. y-...
A 0.25 kg ball moving at a speed of 3 m/s, along the positive x-axis, strikes a stationary horizontal ball of mass 0.30 kg. (a) If the collision is perfectly inelastic, what is the velocity and direction of the balls? (b) If the second ball moves at a rate of 1 m/s towards the positive x-axis, what is the velocity and direction of the first 2. ball after collision?
A 2-kg block moving in the positive x direction with a speed of 5.0 m/s collides with a 3-kg block moving in the same direction with a speed of 2.0 m/s. After the collision the 3-kg block moves at 4.2 m/s. Find the velocity of the 2-kg block after the collision. Is the collision elastic or inelastic? Justify your answer.
A billiard ball of mass = 300.0 g moving with an initial speed of 1.80 m/s strikes a second ball of mass mg 400.0 g initially at rest, As a result of the collision, the first ball is deflected off at an angle of 25.0 0 with a speed of 1.00 m/s. Do not assume this is a perfect collision, (a) Taking the x-axis to be the original direction of the motion of ball A, write down the equations of...
A cue ball moving at 2.8 m/s collides elastically with a stationary 8 ball of identical mass. The 8 ball then moves away at an angle of 28 degrees from the direction of the incoming cue ball. What is the speed of the cue ball after the elastic collision?
