3. A block of mass m1 = 250g is at rest on a plane that makes an angle 0 = 30 ° about the horizontal. The coefficient of kinetic friction between the block and the plane is µc = 0.100. This block is attached to a second block of mass m2 = 200g that hangs freely from a rope that passes from a pulley without friction and with negligible mass. When the second block has fallen 30 cm, its speed is; a, 83 cm / s b. 160 cm / s 30

Jason is pulling a box across the room. He is pulling with a force of 24 newtons and his arm is making a 69 angle with the horizontal, what is the horizontal component of the force he is pulling with?

A bag of cement weighing 525 N hangs in equilibrium from three wires as suggested in the figure below. Two of the wires make angles ?1 = 61.0° and ?2 = 42.0° with the horizontal. Assuming the system is in equilibrium, find the tensions T1, T2, and T3 in the wires. T1 = N T2 = N T3 =.

Question 3. The cart shown in figure below moves with constant deceleration changing the speed from v0 = 5 m/s to v1 = 1 m/s. After 2 seconds when it reaches the speed v1 it suddenly stops. Write the displacement of the mass as a function of time. Mass m moves without friction on the surface of the cart. Assume positive direction from left to right (direction of motion of the cart). Numerical values: m = 2 kg, k = 1.152 kN/m. V k Ans: x(t) = 3.472 cos 24 t + 41.6 sin 24 t (mm) m L

A warehouse worker pushes a crate along the floor, as shown in the figure (Figure 1), by a force of 19 NN that points downward at an angle of 45 degrees below the horizontal. Find the horizontal component of the push. Your answer should be positive if the force is to the right, negative if the force is to the left. Express your answer in newtons.   Find the vertical component of the push. Your answer should be positive if the force is upward, negative if the force is downward. Express your answer in newtons.

1. A 20,000 pound truck is parked on a 15° slope. Find the force required to keep the truck from rolling down the hill (that is, find the magnitude of the vector component of the weight of the truck that is parallel to the slope). 2.Determine the vector v with magnitude of 30 that makes an angle of 120° with the positive xaxis. State the vector in either ordered set or unit vector notation with components written as exact values (simplified radical form).

Two people play tug of war. The 100-kg person on the left pulls with 1100 N, and the 75-kg person on the right pulls with 870 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons? Add your answer
