a block of plastic and a block of lead each 0.2kg are released simultaneously and fall down a well with water at the botton. The lead block took 4.0s to reach the water surface. State and explain the difference in the time of arrival of the two blocks at the surface of the water. Calculate the speed with which the lead block strikes the water. find the distance of the water surface from the top of the well​
