3. A stone of mass 56g is thrown horizontally from the top of a clic with a speed of 18 ms'l, as illustrated in Fig. 4.1. 16m sea level Fig.4.1 The initial height of the stone above the level of the sea is 16m. Air resistance may be neglected. (a) Calculate the vertical component of the velocity of the stone just as it hits the water. (b) State the horizontal velocity of the stone as it hits the water. (c) Draw a vector diagram to represent the horizontal velocity and the resultant velocity of the stone as it hits the water. (C!) Show that the speed of the stone as it hits the water is approximately 25 ms'l. (e) Determine the angle with the horizontal at which the stone hits the water
