A man moving with a speed v down the inclined plane meets the rain horizontally with same speed .The actual velocity of rain is

A man standing on a inclined plain observes rain is falling verticaly. When he starts moving down the inclined plain with velocity v=6m//s observes rain hitting him horizontally. The actual velocity of rain is

A ship X moving due North with speed v observes that another ship Y is moving due West with speed v. The actual velocity of Y is

A man standing on a inclined plain observes rain is falling vertically. When he starts moving down the inclined plain with velocity v=6m//s observes rain hitting him horizontally. The velocity of rain with respect to the man when he is moving down is

A block of mass m moves with constant speed down the inclined plane of inclination theta . Find the coefficient of kinetic friction.

A man is running up an inclined plane ( making an angle theta with the horizontal ) with a speed u. Rain drops falling at an angle alpha with the vertical appear to the man as if they are falling at an angle of 45^(@) with the horizontal . The speed of the rain drops is

Rain is falling vertically downwards with respect to ground. If a girl running on the ground with speed 3 km/h observes the rain is falling with speed 5 km/h then actual speed of rain is

A man is moving due east with a speed 1 km/hr and rain is falling vertically with a speed sqrt(3) km/hr. At what angle from vertical the man has to hold his umbrella to keep the rain away. Also find the speed of rain drops w.r.t. man.

As shown in the figure a body of mass m moving vertically with speed 3 m/s hits a smooth fixed inclined plane and rebounds with a velocity v_(f) in the horizontal direction . If angle of plane with horizontal is 30^(@) , the velocity v_(f) will be

Rain is falling vertically downward with velocity 4m//s. A man is moving horizontally with velocity 3 m//s , the velocity of rain with respect to man is

To a stationary man, rain appears to be falling at his back at an angle 30^@ with the vertical. As he starts moving forward with a speed of 0.5 m s^-1 , he finds that the rain is falling vertically. The speed of rain with respect to the moving man is.
