(1) Of the curves shown in the figure above, which best describes the path followed by the apple as seen by a stationary observer on the ground, who observes the truck moving from his left to his right? O (a) O (b) O (c) O (d) O (e) (u) of the curves shown in the figure above, which best describes the path as seen by an observer sitting in the truck? O (a) O (b) (c) O (d) 0 (e) A polar bear is sitting on a sheet of ice that is being carred by the current away from the north pole at a speed of I m/'s, A fish is swimming toward the north pole at a speed of 10 m/s relative to the current. What is the speed of the fish with respect to the north pole?

Explanation / Answer

1. For the stationary observer on ground path of apple will be a parabola . It is because apple has horizontal velocity equal to that of truck and a downward acceleration. Therefore option (a) is correct

2. for a observer inside truck horizonyal velocity of apple is zero. So he finds appple to be falling verticaly downwards. Therefore option (b) is correct.
