a point object is thrown vertically upward at such a speed that it returns to the thrower after 6 sec? with what speed was it thrown up and how high did it rise? plot speed time graph for the object and use it to find the distance travelled by it in last second of its journey.
the motion of a particle along x-axis is given by y=9+5t2 where x is distance in cm and t is time in second. find (i) displacement after 3 s & 5s.. (ii)av.velocity during the interval t=3 s to t=5 s . (iii) instantaneous velocity at t=3s.
