Question

TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.

21) The kinetic coefficient of friction is usually larger than the static coefficient of friction.

22) A book can slide down a frictionless hill at constant velocity.

23) Your mass on the moon will be about one-sixth of your mass on Earth.

24) The vertical component of the acceleration of a projectile remains constant during the entire trajectory of the projectile.

25) The horizontal component of the velocity of a projectile remains constant during the entire trajectory of the projectile.

21 )

False , because kinetice friction work when object move and static friction work when it not moving .

22 )

false , because on hill there always gravitational acceleration work , for constant velocity particle should not accelerate

23 )

false , mass remain constant it doens not depend on g weight will be different

24 )

false , because in vertical direction always g works , it can not be constant

25 )

True

in horizontal direction there no force is working , so particle goes by constant velocity
