Q1. You tie a rope to a tree and you pull on the rope with a force of 100 N.   What is the tension in the rope?

Q2. Antilock brakes keep the car wheels from locking and skidding during a sudden stop. Why does this help slow the car down?

Q3. A mass m is placed on an inclined plane (m > 0) and slides down the plane with constant speed. If a similar block (same m) of mass 2mwere placed on the same incline, what is true in this case?

Q6. A 200 gram ball is thrown with a speed of 16 m/s and at an angle of 22 degrees off a cliff. If the ball hits the ground 6.4 seconds later, how much kinetic energy it would have just before it hit the ground?

Explanation / Answer

Here ,

let the tension is T ,

now , force applied , F = 100 N

as the rope is in equilibrium ,

F = T

T = 100 N

the tension in the rope is 100 N

2)

this helps car stops because static frictional force is larger than kinetic frictional force .
