1 pts Question 1 Why should the block move at constant velocity idue to the pull of the hanging weight) when finding kinetic friction (procedure 2) Because acceleration wili add another force pulling the tlocktnad tion to the tenon in the string) velocity b fot (otliLLhe 1ersion in the strir vil become zero. 9 Constant velocity meas eno acceterwion meas Tension Friction force Becaan we cannot measure Keeraurt Question 2 2 pts f Ind the horzontal torce needed to put a muss of 30 ke at constant velocity on a level surface and wah 03 Question

Explanation / Answer

A> Answer is C i.e Constant Velocity means Zero accelaration, hence, tension = friction force

B> Horizontal force required = 30 * 9.8 * 0.3 = 88.2N. So C
