A man moving in rain holds his umbrella inclined to the vertical even though the rain drops are falling vertically downwards. Why?

A man standing on a road has to hold his umbrella at 30^0 with the vertical to keep the rain away. The throws the umbrella and starts running at 10 km/h. He finds that raindrops are hitting his head vertically. Find the speed of raindrops with respect to a. the road, b. the moving man.

A man of mass m having a bag ofmas m slips from the roof of atall building of height H and starts falling vertically figure. When at a height h from the ground, he notices that the ground below him is pretty hard but there is a pond at a horizontal distnce x from the line of fall. In order to save himself he throws the bag horizontally (with respect to himself) in the direction opposite to the pond. Calculate the minimum horizontal velocity imparted to the bag so that the man lands in the water. If the man just suceeds toavoid the hard ground, where will the bag land?

Why are rain drop spherical in nature?

A ball is dropped from a height of 19.6 m above the ground. It rebounds from the ground and raises itself up to the same height. Take the starting point as the origin and vertically downward as the positive X-axis. Draw approximate plots of x versus t, v versus t and a versus t. Neglect the small interval during which the ball was in contact with the ground.

A man should hold his umbrella with vertical, when rain fals vertically with velocity V_(R) and man walk horizontally with velocity V_(M) . It's direction is given by :

Which fall faster-big rain drops or small rain drops?

A man running on the horizontal road at 8 km h^(-1) find the rain appears to be falling vertically. He incresases his speed to 12 km h^(-1) and find that the drops make angle 30^2 with the vertical. Find the speed and direction of the rain with respedt to the road.

Give the magnitude and directions of the net force acting on a rain drop falling with a constant speed.
