What is the magnitude of the upward acceleration of the load of bricks? (Express your answer in meters per second.) What is the tension in the rope while the load is moving? (Express your answer in newtons.)

This problem pertains to the diagram on the right.  Two dock workers pull a 1500 kg boat.                  a)  What is the sum of force A and force B? Give the x and y components, in units of Newtons.                b)  What is acceleration of the boat? Give the x and y components, in units of m/s2.                c)  What is the magnitude of the boat’s acceleration, in units of m/s2?                d)  What is the direction of the boat’s acceleration? Give your answer as an angle measured relative to the x axis.

You are camping in bear country and you are setting up your camp for the night. You string up your food, as shown in the picture below, so that the bears in the area do not steal it. The breaking tension of the type of string you are using is 800 Newtons. Any tension greater than that will cause the string to snap. The mass of your food pack is 10 kg. If a bear comes along in the night and pulls straight down on the food pack, with what maximum force can it pull before the strings snap?

How would I draw the vectors for trial 1 and trial 2 on a graph?

A 1,040-N crate is being pushed across a level floor at a constant speed by a force  F  of 390 N at an angle of 20.0° below the horizontal, as shown in the figure a below. Two figures show a side view of a crate positioned upon a horizontal surface. Figure (a): An arrow pointing downward and to the right is labeled vector F and forms an angle of 20° below the horizontal as it approaches the upper left edge of the crate. Figure (b): An arrow pointing upward and to the right is labeled vector F and forms an angle of 20° above the horizontal as it extends from the upper right edge of the crate. (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.)(b) If the 390-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a).

The pair of pulleys is used to lift a 40-kg block 0.25 m. The constant upward acceleration of the block during the lift is +2.5 m/s^2, and the pulleys and rope have negligible inertia and negligible friction. A. What is the tension in the pulling rope? Express your answer with the appropriate units. B. What is the tension in the rope from which the block hangs? Express your answer with the appropriate units. C. Determine the magnitude of the force exerted by the upper mount on the top pulley. Express your answer with the appropriate units. D. How much work is done by the person pulling the rope in lifting the block 0.25 mm? Express your answer with the appropriate units. E. By how much does the kinetic energy of the block change in this process? Express your answer with the appropriate units. F. How much work is done on the block by the rope attached to it? Express your answer with the appropriate units. G. How much work does the ceiling do in this process? Express your answer with the…

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

in Monkey and hunter case . my doctor want me to write a 5 lines about what I have learned from this screenshot. ( The simulation shows the classic physics situation of a monkey and hunter. In this case, the hunter is trying to tranquilize the monkey, so the monkey can be relocated to a better habitat. The monkey is clever—when the tranquilizer dart (in blue) leaves the gun, the monkey (in purple) lets go of the tree branch, and starts to fall straight down. Note that there is a net (not shown) at the bottom to catch the monkey, so the monkey won't get hurt.)

A 5.0 kg object has a set of three forces acting on it, as shown in the diagram. At t = 0, the object is located at the origin and is at rest.                  a)  Use Newton’s second law to find the acceleration of the object. Give both the magnitude and the direction (relative to the +x axis).               b)  What is the velocity of the object at t = 7.50 seconds? Give both the magnitude and the direction (relative to the +x axis).               c)  How far is the object from the origin at t = 7.50 seconds?

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
