Transcribed Image Text:7. Two particles P and Q that are moving along a straight line collide at
time t = 0.
• Particle P has mass 7,61 kg and was moving with constant velocity
UP/O (t < 0) = (3,86 m/s) i before the collision.
• Particle Q has mass 9,54 kg and was moving with constant velocity
vo/o(t < 0) = (2, 32 m/s) i before the collision.
If the coefficient of restitution between the particles is e = 0,34 and the
particles are constrained to move along the same straight line after they
collide, then the velocity of particle P after the collision is:
(a) Up/o (t> 0) = (2,71 m/s) i
(b) up/o(t > 0) = (3, 47 m/s) i
(c) 2p/o (t> 0) = (2,88 m/s) i
(2,56 m/s) i
(d) up/o (t> 0) =
(e) v p/o (t> 0) = (4,05 m/s) i
(All the above numbers have been rounded to two decimal places.)
