In a tennis match Maria Sharapova returns an incoming ball at an angle that is 4° below the horizontal at a speed of 15 m//s . The ball was hit at a height of 1.6 m above the ground. The opponent, Sania Mirza, reacts 0.2 s after the ball is hit and runs to the ball and manages to return it just before it hits the ground. Sania runs at a speed of 7.5 m//s and she had to reach 0.8 m forward, from where she stands, to hit the ball. (a) At what distance Sania was standing from Maria at the time the ball was returned by Maria? Assume that Maria returned the ball directly towards Sania. (b) With what speed did the ball hit the racket of Sania? [g = 9.8 m//s^(2)]

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student speculates that the constant C depends on :- (i) The angle at which the ball was launched (ii) The ball's mass (iii) The ball's diameter If we neglect air resistance, then C actually depends on :-

The student performs another trial in which the ball is launched at speed 5.0 m//s . Its range is approximately:
