Question 1 1 pts A 6.41kg mass is initially at rest on a frictionless plane inclined at an angle 27.91 to the horizontal. The length of the plane is 114711. Determine the magnitude of the force causing the mass to slide down the plane once released from rest (in N]. (use 9 = 9'32?\" as the magnitude of the acceleration of gravity) Question 2 1 pts A 20kg mass is being lowered by a rope. The mass is accelerating downward with an E 9.8m acceleration of magnitude 1.975 52 . Determine the tension in the rope (in M. (use 9 = 52 as the magnitude of the acceleration of gravity} Question 3 1 pts A 4.86kg mass is initially moving with a velocity 7.97(m/s)% on a horizontal plane. The coefcient of kinetic friction is 0.361. Determine how far the mass moves before coming to rest (in m). (use 9 : 932m as the magnitude of the acceleration of gravity) Question 4 1 pts A block ofm 211.8369 is being pulled up an inclined plane by a rope (parallel to the incline} at an initial speed of 2.51m/3 and slowing down at a rate of 0.844%. The plane is inclined at an angle of 24.80369 to the horizontal. The coefcient of static and kinetic friction are #3 = 0.55 and pk = 0.4. Determine the magnitude of the tension in the rope (in N). Question 5 1 pts The figure shows a 100kg block being released from rest from a height of 1.0m. It then takes it 10.421s to reach the floor. Determine the tension in the rope while the masses are in motion (in NV ). The pulley has no appreciable mass or friction 100 kg 1.0 m Question 6 1 pts A 23.49kg sign is held by two ropes as shown in the figure. What is the tension on rope B (in N)? B 50 30Question 15 1 pts A 18.11;;r mass on the end of a 46.9cm string is rotated in a horizontal circle. The string breaks if the tension exceeds 27.8N. Determine the maximum rotation speed of this mass (in RPM). Question 16 1 pts A 1.20.3139 mass is initially at rest on a frictionless plane inclined at an angle 24.858 to the horizontal. The length of the plane is 4.17m. Determine the time it takes the mass to slide down 9.8m 32 the plane once released from rest (ins). [use 9 = as the magnitude of the acceleration of gravity)
