An object of mass m1 slides on a sloped block of mass M2, which in turn slides on a horizontal surface. The slope angle is a constant 3, and both masses are initially at rest. There is no friction between any of the objects, and the masses are subject to the force of gravity -mgêy. Use as co- ordinates the horizontal position x2 of mass m2, and the height y1 of mass m1, as shown in the y4 Y1 M2 x2 diagram to the right. Find the equation of motion of block 2, ä2(t). The expression should only include expressions involving constants: M2, m1, g, and B.
A block A of 60.0 lb is connected to a block B of 10.0 lb by means of a rope and an ideal pulley. The system is released from rest. Between block A and the surface, there is a coefficient of kinetic friction of 0.10. Block A has descended 5.00 ft. At this moment, determine: a. The displacement of block B.b. The magnitude of the tension in the rope.c. The speed of block B.d. The speed of block A.
Q.1. A block of mass m = 0.5 kg is pushed against a horizontal spring of spring constant k = 450 N/m and negligible mass. The spring is compressed a distance x from equilibrium, and then released from rest. The block travels along a frictionless horizontal surface and reaches point B with a speed vg = 12 m/s. Take g = 10 m/s2. The compression of the spring is: a. x = 0.16 m b. x = 0.467 m c. x = 0.533 m B. d. x = 0.4 m

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 -

Part A The system is released from rest at 0= 0° when a constant couple moment M = 100 N·m is applied. (Figure 1) If mass of the cable and links AB and BC can be neglected, and each pulley can be treated as a disk having a mass of 6 kg, determine the speed of the 20-kg block at the instant link AB has rotated 0-90°. Note that point C moves along the vertical guide. Also, the cable does not slip on the pulleys. Express your answer to three significant figures and include the appropriate units.

1) A loaded wheelbarrow is pulled to the left with an acceleration a = 2 m / s2 by a force P. In this motion, the wheelbarrow does not rotate and the force of friction as well as the effect of the rotation of the wheel may be neglected. The combined mass of the wheelbarrow and its load is 250 kg with center of mass at G. For this instant, determine the horizontal and vertical components of the force P and the normal reaction at B. a P G 60 cm 50 cm 1 m 20 cm
