Lesson 4 Homework 1. A pitcher throws a fast ball with a horizontal velocity of 125 kmh -1 towards the home plate which is 18.5 m away. Neglecting air resistance, find (i) the time taken by the ball to reach just above the home plate, (ii) the vertical drop of the ball during this time. 2. A spring loaded gun placed on a table 1.0 m above the ground level projects a marble with an initial speed of 4.8 ms -1 . (i) What is the time taken by the marble to drop to the ground? (ii) How far from the table will the ball fall? 3. A ball rolls with a constant velocity of 1.5 ms -1 at an angle of 45 o relative to the x-axis in the 4 th quadrant. Taking the ball to be at the origin at t = 0, what is its position ( x and y co-ordinates) at t = 1.65 s? What is the displacement of the ball at this time? 4. The y component of a velocity that has an angle of 27 o with the x-axis has a magnitude of 3.8 ms -1 , (a) What is the magnitude of the velocity? (b) What is the magnitude of the x-component of the velocity?
