Hola Brainlians !!!
An object is kept fixed at point x = 3 and Y = 1.25m on a plank p raísed above the ground .At time t = 0 the plank starts moving along the +x direction with an acceleration of 1.5 m/s² . At the same ínstant a stone is projected from the origin with a velocity u as shown . A stationary person on the ground observes the stone hitting the object during its downward motion at an angle of 45° to the horizontal .All the motions are in the x-y plane find u and the time after which the stone hits the object .
( Take g = 10m/s )
