A student hits a board with an initial speed of 10.0 m/s. The student's hand and the board are in contact for 0.002 second and the speed of the hand decreases to 1.0 m/s during the contact between the board and the hand (the hand is aļways moving forward). The mass of the student's hand and arm is 1.0 kg, and the board has a cross-sectional area A = 10.0 cm². £stimate the shear stress on the board.

Three beads are placed along a thin rod. The first bead, of mass m1 = 25 g, is placed a distance d1 = 0.75 cm from the left end of the rod. The second bead, of mass m2 = 11 g, is placed a distance d2 = 1.8 cm to the right of the first bead. The third bead, of mass m3 = 48 g, is placed a distance d3 = 3.9 cm to the right of the second bead. Assume an x-axis that points to the right. -Find the center of mass, in centimeters, relative to the left end of the rod. (Xcm = ?)

Problem B2. A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill fromn a height h = 2.00 m to the base, where it meets a rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. Figure B2. Problem diagram B2 b) Find the speed with which the box and the plank move together.
A 2.0-m-long rod has a density in kilograms per meter A = a + bx ,where a = 1.0 kg/m, b = 1.0 k9/m², and x is the distance from the left end of the rod. The rod rests horizontally with each end supported by a scale. The force exerted by the left scales is 39.2 N 22.9 N 16.3 N 4.0 N 32.6 N
A 7.0 g bullet is fired into a 1.5 kg block and becomes embedded in the block. After the collision, the block slides 2.80 m up an incline of 30 degrees with a surface that has a coefficient of kinetic friction of 0.25. How fast was the bullet traveling prior to striking the block?
An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 124 kg and the bag of tools has a mass of m = 13.0 kg. If the astronaut is moving away from the space station at Vj = 1.20 m/s initially, what is the minimum final speed vpf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f = m/s
In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture. The tire remains stationary in spite of the three pulls. Alex pulls with force F→A of magnitude 202 N, and Charles pulls with force F→C of magnitude 189 N. Note that the direction of F→C is not given. What is the magnitude of Betty's force F→B if Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium?
A person is crossing a bridge. The bridge is 3.2 meters long and is 25 kg. One side of the bridge rests on the ground while the other side of the bridge is elevated 25 degrees above the ground. The end of the bridge that is elevated is connected to a rope, which is attached to a overhanging section of a cliff. The person walking across is 62 kg, and walks three quarters of the way to the rope end of the bridge then stops. Please determine the magnitude of the force that the ground exerts on the bridge.

7. A 730-N man stands in the center of a frozen pond of radius 5.00-m. There is no friction between the man's shoes and the ice, preventing him from walking off of the pond. The man then picks up a 1.20-kg rock lying beside him and throws it horizontally at a speed of 5.00-m/s. How long does it take the man to reach the edge of the pond? Answer: 61.7 s
In a train crash, a train of mass 1.85 x 104 kg collides with a stationary train of mass 2.20 x 104 kg at a speed of u = 20.0 ms-1. Filling the crash, they connect and move at the same speed. There is no friction. The train driver blows a whistle which is open at one end and closed at the other. It has a length of 0.480m . The speed of sound in air is 343 ms-1. 1. Draw a diagram of the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Label the open and closed ends of the whistle. 2. calculate the frequency of the sound made by the whistles fundamental resonance.
An interacting system of two objects has no external force acting on the system. The firstobject has a mass 2.00 kg and is moving with a velocity (2.00 m/s)i + (1.00 m/s)j at time t =0.00 s. The second object has a mass 3.00 kg and is moving with a velocity (-1.00 m/s)i +(1.00 m/s)j at time t = 0.00 s. The second object is moving with a velocity (2.00 m/s)i +(-1.00 m/s)j at time t = 1.00 s. What is the velocity of the first object at t = 1.00 s?
