The lighter dart leaves the spring moving faster than the heavy dart -
answer-A heavy dart and a light dart are launched horizontally on a
frictionless table by identical ideal springs. Both springs were initially
compressed by the same amount. Which of the following statements
about these darts are correct? (There could be more than one correct
choice.)
four times that of Bill's ball. - answer-Joe and Bill throw identical balls
vertically upward. Joe throws his ball with an initial speed twice as high
as Bill. If there is no air resistance, the maximum height of Joe's ball will
be
Both otters have the same speed at the bottom. - answer-Two frisky
otters slide down frictionless hillsides of the same height but different
slopes. The slope of the hill of otter 1 is 30°, while the slope of the hill
of otter 2 is 60°. If both start from rest, which otter is moving faster
when she reaches the bottom of her hill?
Both do zero work. - answer-Person X pushes twice as hard against a
stationary brick wall as person Y. Which one of the following
statements is correct?
, The 500-kg object - answer-Which one has larger kinetic energy: a 500-
kg object moving at 40 m/s or a 1000-kg object moving at 20 m/s?
The work could be either positive or negative, depending on the
direction the object moves. - answer-If the force on an object is in the
negative direction, the work it does on the object must be
4H - answer-When you drop a pebble from height H, it reaches the
ground with speed V if there is no air resistance. From what height
should you drop it so it will reach the ground with twice speed?
The speed will be the same in all cases. - answer-A girl throws a stone
from a bridge. Consider the following ways she might throw the stone.
The speed of the stone as it leaves her hand is the same in each case.
Case A: Thrown straight up.
Case B: Thrown straight down.
Case C: Thrown out at an angle of 45° above horizontal.
Case D: Thrown straight out horizontally.
In which case will the speed of the stone be greatest when it hits the
water below if there is no significant air resistance?
They both slide to exactly the same height. - answer-A lightweight
object and a very heavy object are sliding with equal speeds along a
