Answer:
4.34 m/s
Explanation:
m1 = 3.4 g
m2 = 0.82 g
u1 = 18 m/s
u2 = 0
θ = 51°
Let the velocities after the collision be v1 and v2 respectively.
Use conservation of momentum along X axis
m1 x u1 + m2 x u2 = m1 x v1 x Cos 51 + m2 x v2 x Cos 51
3.4 x 18 + 0 = 3.4 x v1 x 0.74 + 0.82 x v2 x 0.74
61.2 = 2.5 v1 + 0.61 v2 ... (1)
Use conservation of momentum along Y axis
0 = m1 x v1 x Sin 51 - m2 x v2 x Sin 51
3.4 x v1 x 0.67 = 18 x v2 x 0.67
2.23 x v1 = 12.06 v2
v1 = 5.41 v2
Substitute in equation (1)
61.2 = 2.5 x 5.41 v2 + 0.61 v2
61.2 = 14.1 v2
v2 = 4.34 m/s
