Answer:
Option(B),option(C) and Option(D) are the correct answer to the given question .
Explanation:
- In the option(B) if we apply the force to stop the car. The motion and force of car is in the opposite direction .Suppose the person is moving the car to the straight and person immediately apply break the back wheel of the car is stop this means that force and direction of motion is opposite that's why this is correct .
- In the option(C) the ball and batsman hinting the ball is in the opposite direction .Suppose the ball is coming to the batsman to the right and it hits to the left its a opposite direction Therefore in this the force and direction of motion is opposite that's why this is correct .
- In the option(D) if the person drawing water from a well there is always upward force is applied but there is always motion is there i.e downward force i,e mg.that's why force and direction of motion is opposite that's why this is correct .
- In the option(A) the force of opening the door of force and the motion is in the same direction therefore it is not the against the direction of motion that's why this option is incorrect .
2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart
