Physics - Velocity

A 5.00kg ball

moving to the right at a velocity of 2.00m/s on a frictionless table

collides head-on with a stationary 7.5kg ball. Find the final velocities of the balls (a) if the collision is elastic and (b) if the collision is pletely inelastic and the o balls moving together.

m1 = 5 kg

u1 = +2 m/s

m2 = 7.5 kg

v1 = 0 m/s

u2 = ?

v2 = ? (a) Since the collision is elastic

kiic energy is conserved m1u1 +m2v1 = m1u2 + m2v2 -------------- (1) ½m1(u1^2) + ½ m2(v1^2) = ½m1(u2^2) + ½m2(v2^2) ----------- (2) From equation (1)

(5kg)(2m/s) +(7.5kg)(0 m/s) = (5kg)u2 + (7.5kg)v2 -------------- (3) 10 + 0 = 5u2 + 7.5v2 2 = u2 + 1.5v2 u2 = 2 - 1.5v2 -------------------------------------- (4) From equation (2) ½(5)(2^2) + ½ (7.5)(0^2) = ½(5)(u2^2) + ½(7.5)(v2^2) 20 + 0 = (5)(u2^2) + (7.5)(v2^2) --------------- (5) Two equations (4) and (5) with 2 unknown

u2 and v2

solve for the unknown Substitute equation (4) into equation (5) 20 = 5(2 - 1.5v2)^2 + (7.5)(v2^2) Multiply the above equation by 2 40 = 10(2 - 1.5v2)^2 + 15(v2^2) Then divide by 5(v2^2) 8 = 2(2 - 1.5v2)^2 + 3(v2^2) 8 = 2[4 - 6v2 + 2.25(v2^2)] + 3(v2^2) 8 = 8 - 12v2 + 4.5(v2^2) + 3(v2^2) 0 = - 12v2 +7.5(v2^2) Multiply by 2 15(v2^2) - 24v2 3v2(5v2 – 8) = 0 5v2 – 8 = 0 v2 = 8/5 = 1.6 m/s From equation (4) u2 = 2 - 1.5v2 = 2 – 1.5(1.6) u2 = - 0.4 m/s in the opposite direction After collision

5 kg ball moves with 0.4 m/s in opposite direction and 7.5 kg ball moves with 1.6 m/s in the same direction. (5 kg ball is bounced backward) (b) Since the collision is inelastic

some kiic energy is lost Let v3 be the final velocity of both balls 5kg)(2m/s) +(7.5kg)(0 m/s) = (5kg)v3 + (7.5kg)v3 10 = 12.5 v3 v3 = 10/12.5 = v3 = 0.8 m/s in the same direction The final velocity of both balls is 0.8 m/s in the same direction 2011-02-23 04:07:38 補(bǔ)充： In part (a)

no where did the question mention that final velocity of 5 kg ball is zero. The assumption is wrong. It is also wrong that kiic energy before collision (10 J) and after collision (6.66 J) is different. Kiic energy must be conserved for elastic collision.

(a) m1u1+m2u2=m1v1+m2v2 5 x 2+7.5 x 0 = 5 x 0 + 7.5 x v2 on solving

v2 = 1.33 m/s; v1 = 0 m/s (b) m1u1+m2u2= (M1+m2)V 5 x 2+7.5 x 0 = (5 +7.5) x V on solving

V = 0.8 m/s
