Two metal balls are the same size but one weighs twice as much as the other. The balls are dropped from the roof of a single story building at the same instant of time. The time it takes the balls to reach the ground below will be:Group of answer choicesabout half as long for the heavier ball as for the lighter one.about half as long for the lighter ball as for the heavier one.about the same for both balls.considerably less for the heavier ball, but not necessarily half as long.considerably less for the lighter ball, but not necessarily half as long.

The two metal balls of the previous question roll off a horizontal table with the same speed. In this situation:Group of answer choicesboth balls hit the floor at approximately the same horizontal distance from the base of the table.the heavier ball hits the floor at about half the horizontal distance from the base of the table than does the lighter ball.the lighter ball hits the floor at about half the horizontal distance from the base of the table than does the heavier ball.the heavier ball hits the floor considerably closer to the base of the table than the lighter ball, but not necessarily half the distance.the lighter ball hits the floor considerably closer to the base of the table than the heavier ball, but not necessarily half the distance.

In the figure provided, three balls of equal masses are released from the same position. If they are released with equal speeds, which ball has the slowest speed when it hits the ground? Ball b has the slowest speed. Ball c has the slowest speed. Ball a has the slowest speed. They all have the same speed.

Two balls of masses in the ratio 1: 2 fall from heights in the ratio 1: 4. The ratio of their momenta with which they strike the ground is01:101:201:301:411:50 pm

wo people stand on different floors of an outdoor stairway. One is 5 m above the ground and the other is 10 m above the ground. The person on the lower floor throws a ball upward with a speed of 8 m/s and the other person just drops hers. Ignoring air resistance, which ball hits the ground at a higher speed? Question 10Answera.The one that is thrown upwardb.They both hit the ground with the same speedc.The one that is dropped

Students performing an experiment for their physicsclass are dropping balls from a height of 10.0 m.Ignore air resistance. (1.6) T/I(a) How long does it take for a ball to hit the ground?(b) What is the final velocity of the ball just before ithits the ground?
