When a car is at rest, its driver sees rain deops falling on it vertically. When driving the car with spped v, he sees that rain drops are coming at an angle `60^@` from the horizontal. On further increasing the speed of the car to `(1 +beta)v`, this angle changes to` 45^@`. The value of `beta` is close to :

A man walking with a speed of 3 km/h finds the rain drops falling vertically downwards. When the man increases his speed to 6km/h he find that the rain drops are falling making an angle of 30^(@) with the vertical . Find the speed of the rain drops ( in km/h)

A man walking with a speed of 3 km/h finds the rain drops falling vertically downwards. When the man increases his speed to 6km/h he find that the rain drops are falling making an angle of 30^(@) with the vertical . Find the speed of the rain drops ( in km/h)

A man running at a speed of 5 km/h finds that the rain is falling vertically. When the stops running, the finds that the rain is falling at an angle of 60^(@) with the horizontal. The velocity of rain with respect to running man is

A man running at a speed of 5 km/h finds that the rain is falling vertically. When the stops running, the finds that the rain is falling at an angle of 60^(@) with the horizontal. The velocity of rain with respect to running man is

A man running at a speed of 5 kmph finds that the rain falls vertically. When he stops running, he finds that the rain is falling at an angle of 60° with the horizontal. The velocity of rain with respect to running man is

A stationary man observes that the rain is falling vertically downwards. When he starts running a velocity of 12 kmh^(-1) , he observes that the rain is falling at an angle 60^(@) with the vertical. The actual velocity of rain is

Rain is falling vertically when car is at rest. When car moves with speed v rain appears at 60 deg with horizontal when car moves with speed ( beta + 1)v rain appears at 45degrees with horizontal.Find value of beta

Rain is falling vertically when car is at rest. When car moves with speed v rain appears at 60 deg with horizontal when car moves with speed ( beta + 1)v rain appears at 45degrees with horizontal.Find value of beta

A car is travelling in steady rain with constant acceleration in a straight line When is begins to move the driver sees that the raindrops make track at an angle of 37^(@) with the vertical on the side window. After 20 sec., the raindrops make track at an angle of 53^(@) with vertical in same direction Find the acceleration of the car in cm//s^(2) Rain is falling at 3 m//s .
