A stone falling from the top of a vertical tower has descended x metre when another is dropped from a point y metre, below the top. If they fall from rest and reach the ground together, show that the height of the tower is (x+y)^(2)/(4x) m .

A sphere A is thrown up with velocity 20m/sec from the ground. Sphere B of same mass is dropped from a height of 80 m simultaneously, at time t = 0 so that both collide in air and stick together. Find the time (in second) after which the combined mass will fall on the ground. (Calculate from t = 0) (g = 10m//"sec"^2)

Two fair dice are tossed simultaneously. What is the probability that the product of the numbers that land showing is at at least 25 ?

Two identiacal masses are as shown in figure. One is thrown upwards with velocity 20 m/s and another is just dropped simultaneously. The masses collide I air and stick together. After how much time the combined mass will fall to the gorund (calculate the time from the starting when the motion was started )
