Two objects with masses of 2.30 kg and 4.85 kg are connected by a light string that passes over a light frictionless pulley to form an Atwood machine, as in Figure 5.14a. ↑ M Į Figure 5.14a (a) Determine the tension in the string. N (b) Determine the acceleration of each object. m/s² upwards (2.30 kg mass) m/s2 downwards (4.85 kg mass) (c) Determine the distance each object will move in the first second of motion if they start from rest. m (2.30 kg mass) m (4.85 kg mass)

You are a bully.  You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground.  Your arm is extended so that it makes an angle 28 degrees with the horizontal.  The dweeb's back is so sweaty with fear that there is no friction between his back and the wall.  What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below.  Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)

I am having trouble with my homework, and it is all one problem. There are multiple parts to this problem. I am not ure if this will count as one question, or many. I don't mind if you subtract a few questions out of my account, because this is a very long problem. Thank you so much for the help. My homework is due in one hour so a quick response would be very greatly appreciated. -Mark 1a. Johnny is pulling a cart (10 kg) to the left with a force of 50 N. There is a force of friction of 40 N acting on the cart. Sketch the free body diagram of the cart.   1b. What is the net force (Fnet) acting on the cart? Include the unit and direction of the net force.    1c. What is the acceleration of the cart? Include the unit and direction of the acceleration.   1d. CLAIM: As a result of the net force in (b), what is going to happen to the motion of the cart? Must describe velocity and direction of the motion.Use word bank below. Word Bank: constant velocity, going faster/slower, to the…

A 80.0 kg mail bag hangs by a vertical rope 3.5 m long. A postal worker then displaces the bag to a position 2.4 m sideways from its original position, always keeping the rope taut.

What is the acceleration and error of acceleration in a hanging system. There is a cart connected to a string on a pulley that accelerates due to a hanging mass. The mass of the cart and the string together is 511+-1g, gravity is 9.8+-0.03, the hanging mass is 55+-1g. Assuming there is no friction.

Two blocks of mass m1 = 0.6 kg and m2 = 2.4 kg are connected by a massless string, as shown in the Figure. They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.27. Calculate the speed of the blocks after they have moved a distance 53 cm. Assume that the pulley is massless and frictionless.

A mass m₁ = 9.00 kg is connected by a light string that passes over a pulley of mass M = 14.0 kg to a mass m₂ = 12.5 kg sliding on a horizontal frictionless surface (see figure). There is no slippage between the string and the pulley. What is the magnitude of the tension that is acting on mass m₂? (The moment of inertia of the pulley is ½/Mr².)

I tried this question and i'm stuck and have no idea how else I can solve this problem can you help me with this?

Math Review Solve the two equations mi + MVi = mf + MVf and i Vi = (f Vf) for (a) f and (b) Vf if m = 2.00 kg, i = 4.00 m/s, M = 3.00 kg, and Vi = 0. (See Section 6.3.)
