Question

A hockey player uses a leaf blower to apply a constant force on a hockey puck. The puck accelerates in a straight line across the ice. Then another player applies an equally strong, constant force on the puck in the opposite direction. How will the puck move in response?

Answer 1

It will stop immediately.
It will not slow down, but continue moving at constant velocity.
It will slow down and eventually stop.
It will slow down, then continue moving at constant velocity.

Answer 2

if there is an equal force on both sides then the puck shall not move

Answer 3

so a?

Answer 4

i belive so

Answer 5

because it couldn't continue to move with equal forces on both sides

Answer 6

hmm alright ill go with a thanks :)

Answer 7

ok good luck

Answer 8

need anymore help?

Answer 9

yeah i do actually

Answer 10

A 250-N box is at rest on a frictionless horizotal floor. Then a person shoves the box with a non-zero force of magnitude P. Which statement best describes the relationship betweeen P and the motion of the box after it was shoved? do you know this one? @g-lax4

Answer 11

need anymore help?

Answer 12

i might, need the answers

Answer 13

The box will move with constant velocity at a speed that is directly proportional to P.
The box will accelerate across the floor at a constant rate that is directly proportional to P.
The box will not move when P < 250 N, but otherwise will accelerate at a constant rate that is directly proportional to P.
The box will begin moving at a speed that is directly proportional to P, then will gradually slow to a halt.

Answer 14

ok be right back

Answer 15

i think the first one's wrong

Answer 16

the first question?

Answer 17

what do you think it is?

Answer 18

yep...it wont stop

Answer 19

so it will not slow down?

Answer 20

a body in moving with constant velocity continues to be move with constant velocity unless acted upon by a net external force

Answer 21

yep

Answer 22

anyone know the second question?

Answer 23

it will accelerate for as long as the the person was shoving....after that it will move at a constant velocity

Answer 24

making sense?

Answer 25

yeah so its A correct?

Answer 26

i mean B lol

Answer 27

yep

Answer 28

no its A

Answer 29

The box will accelerate across the floor at a constant rate that is directly proportional to P. oh so its not this one right

Answer 30

yeah...once the "shoving" is done...there is no force being applied on the box. so it has to move at a constant velocity.

Answer 31

thanks!

Answer 32

sure :) is this homework?
