Question
I just wanted to check on here with answers from everyone else
True or False:
1)The total distance traveled by a dog must be greater than the magnitude of net displacement in the same journey
2) The instantaneous velocity of the dog at any moment cannot be greater than the average velocity of the entire journey
3) If the dog has a constant speed throughout its journey, then its acceleration must be zero
4) if a ball is thrown straight up, the acceleration of the ball at its maximum height is less than its acceleration at the midpoint on its way down
5) if two objects of different masses are dropeed from the roof of a building at the same time, then the both objects reach the ground simultaneously but with different speeds
Explanation / Answer
1) False, it can be equal to the displacement as well
2) True
3) False. accelearion is the rate of change of velocity not speed
4) False. acceleration always remains constant and equal to g (9.8 m/sec^2)
5) False. They will reach the ground with same speed
