Net Force and Kinetic Friction
A 500 g block is moving at an initial velocity of 2 m/s on a horizontal surface. The coefficients of static and kinetic friction are μₛ = 0.4 and μₖ = 0.3, respectively. A horizontal force of 1.5 N is applied to the block in the direction of its motion. Which of the following describes the block’s velocity?
A
The velocity remains constant
B
The velocity increases
C
The velocity decreases but the block doesn’t stop
D
The velocity decreases until the block stops
