Question

A particle of mass m is moving with horizontal speed 6m/sec as shown in figure. If m<<M then for one dimensional elastic collision, the speed of lighter particle after collision will be (in SI unit)

​

Answer 1

Step-by-step explanation:

speed of lighter particle = V1 m/s

after collision

V1=

u

(m1–m2)(m1+m2)

1+

(m1+m2)

(2m2u2)

here m1=m,m2=M

given m<<M

hence

m1=0

V1=–u1+

M

(2M)

u2

V1=–u1+2u2

V1=–5+(2)(3)

V1=1m/s

lighter particle will move in original direction with speed 1m/s

Answer 2

Mass - weight
