A body of mass 4.7 kg makes an elastic collision with another body at rest and continues to move in the original direction but with 1/3 of its original speed. (a) What is the mass of the other body? (b) What is the speed of the two-body center of mass if the initial speed of the 4.7 kg body was 6.6 m/s?
A body of mass 2 kg makes an elastic collision with another body at rest and continues to move in the original direction but with one-fourth of its original speed. a. What is the mass of the other body? b. What is the speed of the two-body center of mass if the initial speed of the 2 kg body was 4 m/s?
1)A ball moving at 19 m/s makes an off-center elastic collision with another ball of equal mass that is initially at rest. The incoming ball is deflected at an angle of 50◦ from its original direction of motion. Find the speed of the first ball after the collision. Answer in units of m/s. 2) Find the speed of the second ball. Answer in units of m/s.
A1 Kg mass moving at 5 m/s makes a center line collision with a 7 Kg mass initially at rest. If 3 the collision is elastic derive the speed of the 1 Kg mass after the collision. What fraction of the total kinetic energv is transferred to the 7 Kg mass? Again box answers. 5Mls
A 1kg mass moving at 5m/s makes a Center line collision with 7 kg mass initially at rest. if the collision is elastic derive the speed of 1kg mass after the collision. What fraction of the total kinetic energy is transfered to the 7kg mass?
A cart with mass 260 g moving on a frictionless linear air track at an initial speed of 1.4 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 0.84 m/s. (a) What is the mass of the second cart? (b) What is its speed after impact? (c) What is the speed of the two-cart center of mass? (a) Number Units (b) Number Units (c)...
A neon atom (m=20.0u) makes a perfectly elastic collision with another atom at rest. After the impact, the neon atom travels away at a 46.1 ∘ angle from its original direction and the unknown atom travels away at a -58.9 ∘ angle. What is the mass (in u) of the unknown atom? [Hint: You can use the law of sines.]
A cue ball traveling at 6.47 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision. 90 ° (correct) (b) Find the speed of each ball after the collision. cue ball m/s target ball m/s
A block of mass m= 4.4 kg, moving on frictionless surface with a speed v1=9.2 m/s makes a sudden perfectly elastic collision with a second block of mass M, as shown in the figure. The second block is originally at rest. Just after the collision, the 4.4-kg block recoils with a speed of vf=2.5 m/s What is the mass M of the second block?
a) A billiard ball at rest is struck by another billiard ball of the same mass whose speed is 6.0m/s. After an elastic collision the striking ball goes off at an angle of 25 degree with respect to its original direction of motion. Find the angle the struck ball makes with this direction and the final speeds of both balls. b) A particle of mass m, moving with a velocity u, makes a head on collision with a particle of...
