Question

physics question inside

Answer 1

the block shown moves with constant velocity on a horizontal surface. Two of the forces acting on the block are shown. A frictional force exerted y the surface is the only other horizontal force acting on the block

What is the frictional force?

Answer 2

Uh...
The question says that the block is moving. It must be moving to the right since 5N > 3N.

Therefore the force of friction is 3N.

Is there more to this question? There doesn't seem to be any calculations involved...

Answer 3

well the choices are
A. 0
B. 2 N, leftward
C. 2 N, rightwarrd
d. slightly more than 2N leftward

Answer 4

I can't see two forces in the figure..

Answer 5

2N

Answer 6

body is not accelerated therefore total force on the body = 0
therefore 3+ frictional force=5 N
anf frictional force=2N @lgbasallote clear?

Answer 7

I don't know but i can't see the magnitude of force towards right! This is what i can see..

Answer 8

@lgbasallote ???

Answer 9

and 2N leftwards

Answer 10

it's actually rightward

Answer 11

and why do you say it's not accelerated?

Answer 12

because it's velocity is constant

Answer 13

a= dV/dt

Answer 14

oh yeah

Answer 15

it said constant velocity

Answer 16

so why is friction rightward?

Answer 17

i guess it would be leftwards.....because it always acts in the direction to that of the opposite direction of motion

Answer 18

and bigger force acts to the right ....so block must be either moving right or probably left ....lol

Answer 19

but my answer key says rightward

Answer 20

well you can say both are right.....it depends on your frame of reference he he :)

Answer 21

so you're saying i can either choose b or c.....

Answer 22

i don't think that's a logical answer....there must be a reason why it's rightward

Answer 23

i dont get what you mean

Answer 24

nope

Answer 25

exactly what i wrote

Answer 26

could be...
