Simple Questions Pt1. These Questions stem from an old exam that i have yet to turn in. It basically easy in some parts, but some questions I am not tos confident in because of my bad track record with confidence in my physics work. By the way the reason why I'm posting the great amount of questions is because of my exams returned back to me so that i could look over it and could maybe get some tutoring with it. So here they are:
True or False:
7. A child riding a horse on a merr go round moving at a constant speed experiences changing velocity. T
8. A balloon filled with water is dripped by prankster from an open window. At the end of 2 seconds the water balloon has an instantaneous speed of about 10 m/s2.
9. The horizantal component of motion of a projectile undergoes acceleration due to gravity.
10. An object thrown into the air at an angle of 25 degrees will have the same range as if it were thrown at an angle of 65 degrees at the same speed.
Multiple Choices:
24. If a flower pot were dropped from a window ledge 200 meters from the ground and another flower pot were horizantally out the window at the same time, which would hit the ground first? (BTW - - I did a physics experiment to this question by placing a coin at the edge of a table and another at a distance behind it and flicking the coin into the other coin and seeing which one his the floor first.) A. Both would hit the ground ath the same time.
26. Some of the following quantities and some are scalar quantities. Circle those which are vector quantities: I circled velocity, force, and acceleration /other choices: time, speed, distance, volume, and mass.
27. (A) A ball is thrown straight up in the air. As the ball rises, does its velocity increase, decrease, or remain the same? Does its acceleration increase, decrease, and remain the same? I said both decreae.
(B) At the top of its path, what is the velocity of the ball? What is its acceleration? I am not sure what their asking, I should assume there asking what is it movement, for that i say the same
(C) As the ball descends, does its . . ( same ending as question (A))
For that I say increased for both.
