Question

Two particles are thrown simultaneously from points A and B with velocities `u_1 = 2ms^(-1) and u_2 - 14 ms^(-1)`, respectively, as shown in figure.

Minimum separation between A and B is
A. 3 m
B. 6 m
C. 12 m
D. 9 m

Answer 1

Correct Answer - A
a. `(x+9)/27 = tan 37^@ = 3//4`
`rArr x = 45/4 m`
Shortest distance
`AM = x sin 53^@ = 45/4 xx 4/5 = 9m` .
