Question

2 particles are projected vertically upwards from points (0,0) & (1,0) with uniform velocity 10 m/s & V m/s respectively, as shown in fig. It is found that they collide after time 't'. Find 'v' & 't'
​

Answer 1

Answer:

Considering motion in horizontal direction,time taken to collide,

t=2103−2v1

t=106−2v22...(1)

In vertical direction, 10×21t−21gt2=2v×t−21gt2

5=2v

v=52

t=56−10222=1.49 seconds
