Question
Can you please check if I got the right answers.In the picture at the right, two cubes of ice are shown after of steel. There is friction, but not much. The smaller cube, u, static friction coeff for ice on steel 0.050 4kinetic friction coeff for ice on steel- 0.030 they have been just placed on a very shallow incline n A, is half as wide, tall and deep as the larger cu made be, B 35. Which cube will have the greater force of friction acting on it? a. A b. B c. Both the same. 36. At what angle of incline will one or both cubes begin to slide? a. 2.9 b.0.050c. 2.8° d. 0.045 e. 6.7 37. Which cube will be more likely to begin sliding first? a. A b.B c. Both the same. 38.Which cube will have the greater net acceleration? a. A b.B c. Both the same. Which cube will have the greater initial gravitational potential energy? a. A 39. Both the same. 40.Which cube will have the greater speed at the bottom of the incline? Both the same. b.B c. a. A b.B c. 41.Which cube will have the greater kinetic energy at the bottom of the incline? a. A b.?. c. Both the same. 42In both of the situations shown at the right, an applied force of 100 N accelerates the 100 N block on top of the table. In which case is the acceleration greater? a. The two-block system on the left side. b. The one-block system on the right side. c. Both systems have the same acceleration. 100N 100 N 100 N 100 I think tvo blocks is harder to pull than one But I'n just a monkey What do I knowi
Explanation / Answer
35] b, as mass of B is more,
36]a, theta = arctan us = arctan 0.05 = 2.9 degree
37] c, both the same
38] c
39]b, mass is larger
40]b,
41]b, mass is larger
42]b, because in two block system, tension will be less than 100N, causing lesser acceleration.
