Dear Student,

Since when the individual keeps running at 6 km/h the rain is by all accounts coming verticaly down in this manner the level part of rain, Vx is 6km/h

When he incrreases his relative speed by 4 km/h with the level segment of rain, it appears to fall at an edge of 30 degrees with the vertical.

It implies the vertical part, Vy is: 4/Vy = tan 30

i.e.

Vy = 6.93 km/h

V = 10.58 km/h

what's more, point of falling is: tan-1(8/6.93).

Cheers!!

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
