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?
37° 37 Vi 1x104 m/s V-2500 m/s V-200 m/s SP2. A fiery 500 kg asteroid is hurtling towards earth at a whapping speed of 200 m/s. Superman comes to the rescue of the planet and flies towards the asteroid as shown in the picture below. Superman has a mass of 100 kg and is flying with an initial speed of 1x104 m/s. After the collisiorn Superman comes to rest and the asteroid breaks into two pieces. Speed of the 200...
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...
