A body is projectd with the velcity ` (U_1)` from the point (A) as shown in Fig. 2. (d). 37. At the same tiem another body uis projected vertcally upwards with the velcoity ` u_2` from the point (B) .What should be the value of ` u_1)//u_1` for both the bodies to collide ?
.

Explanation

The two bodies will collide, if they reach at a point acquiring the same vertical distance in the same time.

`y = u_(1) sin 60^(@) xx t -1/2 "gt"^(2) = u_(2)t -1/2 "gt"^2`
or `u_(1) xxsqrt3/2 xx t =u_(2) t " or " u_(1)/u_(2) = 2/sqrt3`
