1.15. Value of g in the CGS system 1.16. Value of g in the MKS system 2. Practice Homework 2.1. A long jumper leaves the ground at angle of 25° above the horizontal at a speed of 12 m/s. (i) What is the maximum height reached, and (ii) what is the range? 2.2. A stone is thrown upward at angle of 35° with a speed of 25 m/s from the top of a 50-m high building. (a) How long does it take the stone to reach the ground? (b) What is the speed of the stone just before it hits the ground? 2.3. Suppose the position of a particle is given as a function of time by r(t) = x(t)i + y(t)j, with x(t) = at +b and y(t) = ct? + d, where a = 1.2 m/s, b = 1.2 m,c=0.150 khatri/DS PAGE 15 2.5. After a ball rolls off the edge of a horizontal table at time t= 0, its velocity as a function of tie t is given by v(t) = 1.2 i-9.8tj. The ball's displacement away from the edge of the table, during the time of 0.4 seconds for which the ball is in flight, is given by 6.0.5 v(t)dt.
