Which of the following statements are true of the horizontal motion of projectiles? List all that apply. *
.
A projectile does not have a horizontal velocity.
A projectile with a horizontal velocity will have a horizontal component of
acceleration
The horizontal velocity of a projectile changes by 9.8 m/s each second.
A projectile with a horizontal component of motion will have a constant horizontal
velocity
The horizontal velocity of a projectile is 0 m/s at the peak of its trajectory.
The horizontal velocity of a projectile is unaffected by the vertical velocity; these two
components of motion are independent of each other.
The horizontal displacement(range) of a projectile is dependent upon the initial
horizontal velocity
As a projectile rises towards the peak of its trajectory, the horizontal velocity will
decrease; as it falls from the peak of its trajectory, its horizontal velocity will
decrease

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
