The 152-lb crate is carefully placed with zero velocity on the incline. What is the acceleration of the block (positive down the incline) if (a) e = 14° and (b) 0 = 22°?

8. The garage door has a weight of 220 lb and a center of gravity at G. The man pushes on it with a horizontal force of 50 lb. olb - slugs A 3 ft 6 ft 6 ft -5 ft a. What is the acceleration of the door? B 12 ft b. How long will it take the man to open the door (move it 12 fe

Please answer neatly and simply! ROUND FINAL ANSWERS INTO 4 DECIMAL PLACES.

5. 1) As shown in the image below, the snowmobile has a weight of 259 lb, centered at G1, while the rider has a weight of 154 Ib, centered at G2. If the acceleration is a = 13.5 ft/s?, dimensions are di = 0.9 ft, d2 = 0.4 ft, d3 = 1.6 ft, d4 = 1.6 ft, and height h of G2 of the rider is 1.8 ft, determine the normal reaction force under the front skid at point B. Assume there is only traction (horizontal) force under the rear tracks, but no friction force under the front skid. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g= 32.2 ft/s2. a G2 G1 h A В dz da -

1. If I want the 100-lb block to move with a constant acceleration of 5 ft/s² up the slope, what is the tension P needed in the cable? 100 lb 30⁰ 30 H₂=0.25

The helical path is wound around the circular cylinder with radiusR . The step h= 2*pi*R. The object A is sliding through the path guide under gravity (acting in the negative zdirection). There is no air resistance 1)Draw the force diagrams in (theta ,Z ) plane (tangent to the cylinder) and in( r,theta ) plane. 2) If the initial speed is 0, find the speed after 3 full circles. Given: R, g, m, u.[Hint: Use the work-energy principle.]

Part A. what is the acceleration of the collar after it has moved 6.25 m?Part B. what is the speed of the collar after it has moved 6.25 m?

Required information The uniform thin rod AB is pin-connected to the slider S, which moves along the frictionless guide, and to the disk D, which rolls without slip over the horizontal surface. The pins at A and B are frictionless, and the system is released from rest. Neglect the vertical dimension of S. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. B D R Letting L = 1.75 m and R= 0.65 m, assuming that S and D are of negligible mass, that the mass of rod AB is MAB= 7 kg, and that the system is released from the angle 0o = 65°, determine the speed of the slider S when it strikes the ground. (Round the final answer to four decimal places.) The speed of the slider S when it strikes the ground is m/s.

Determine the tension P in the cable which will give the 79-lb block a steady acceleration of 4.1 ft/sec2 up the incline.
