Question
1st block is 5kg, 2nd is 1kg, and 3rd is 3kg, the tension is 50N. The "50N" should be written beside the last arrow. A "T" is written next to 1st arrow.
1. If the y axis is vertical and x axis is horizontal the summation of forces in y direction is equal to zero? T/F
2. If the y axis is vertical and x axis is horizontal the summation of forces in x direction is equal to zero? T/F
3. If the y axis is in the vertical direction and the x axis is in the horizontal direction, the net force in the x direction for the 3 kg block is 50N? T/F and please explain
4. If the y axis is in the vertical directions and the x axis is in horizontal , and if the coefficient of static friction is 1.0 for all blocks, the blocks would not move? T/F and please explain
5.If the y axis is in the vertical direction and the x axis in horizontal, the normal force on the 1kg block is 9.8N?
Explanation / Answer
Given: 1st block mass = m1 = 5 kg 2nd block mass = m2 = 1 kg 3rd block mass = m3 = 3 kg (1) If the y axis is vertical and x axis is horizontal the summation of forces in y direction is equal to zero. it is TRUE (2) If the y axis is vertical and x axis is horizontal the summation of forces in x direction is equal to zero since ,forces are acting along the horizontial it is FALSE (3) If the y axis is in the vertical direction and the x axis is in the horizontal direction, the net force in the x direction for the 3 kg block is 50N it is FALSE (4) If the y axis is in the vertical directions and the x axis is in horizontal , and if the coefficient of static friction is 1.0 for all blocks, the blocks would not move , since , frictional force fK = s (N) = s (mg) If s = 1 , then fK = mg TRUE (4) If the y axis is in the vertical directions and the x axis is in horizontal , and if the coefficient of static friction is 1.0 for all blocks, the blocks would not move , since , frictional force fK = s (N) = s (mg) If s = 1 , then fK = mg TRUERelated Questions
