Assuming that the object started at rest, calculate the net acceleration using v^2=u^2+2as.Now divide g into horizontal and vertical components. Take frictional force along the plane opposite to the direction of motion. Net acceleration a=g.cos 45°-f, where first is frictional retardation. Find...
Does the understanding and application of physics and fundamental chemistry is only required to be physicist? Or you have to be be equally apt in chemistry??
