Students are to perform an experiment to determine the acceleration due to gravity, g, in the lab by plotting data in a graph. The students have access to equipment commonly found in a high school physics laboratory, but the experiment must use the setup as shown above, which includes a dart of mass m1 and a block of mass M2 hanging from the ceiling by light strings with negligible mass. The dart is launched with a speed of v towards the block. Assume that the velocity of the dart is horizontal when it collides with the block.

The fish is a real lunker and has a mass of m = 9.1 kg. a) What is the displacement vector for the fish during this time interval? Express your answer using unit-vector notation (i.e. ->Ar = _î + __j) (6 m, 0 m) |(3 m, -2 m) Suppose the river exerted a constant force of F* = (28 N)î – (14 N)ĵ on the fish as it moved toward the hook. b) How much work was done on the fish by the river?In this problem, we will consider the following situation as depicted in the diagram: A block of mass m slides at a speed v along a horizontal smooth table. It next slides down a smooth ramp, descending a height h, and then slides along a horizontal rough floor, stopping eventually.

The magnitude of the force is given as F = 4t, and has units of newtons. Let the x-axis point towards the East. Determine the change in x-coordinate in meters of the particle Δx between t = 0 and t = 2.4 if the initial velocity is 17.5 m/s, and pointed in the same direction as the force.2.3. A train car is sitting on a level track when a second car moves in. The second car hits the first, their hitches engage, and they move together.

- This problem pertains to the scenario depicted in the diagram below, where the masses of the blocks are mi = 9.50 kg and m2 = 7.50 kg , and the angle of the ramp is 0 = 27.5°. There is no friction between block 2 and the ramp, but there is friction between block 1 and the flat surface it rests on. When the system is set in motion, both blocks move to the right at a constant speed. What is the coefficient of kinetic friction between block 1 and the flat surface (uk)? Show all steps, including drawing free body diagrams and applying Newton's 2nd law to each block. Problem 4 %3D sliding at constant speed m1 sliding at m2 constant friction no speed friction here hereHere we have a block of mass (m=2.50kg) resting on a place inclined at an angle of ø=30° to the horizontal. The coefficient of static friction between the block and the plane is Ustatic = 0.135 and the block is stationary but just on the point of sliding up the slope. The diagram shows the four forces acting on the block: an applied force F1 acting up the slope, the block's weight mg, the normal reaction force N and the force of static friction, Ff. In this case, the force of static friction acts down the slope, opposing the tendency of the block to move up the slope. Find the the maximum magnitude of the applied force F1 that can be exerted if the block is to remain stationary.k A 13.00 kg particle starts from the origin at time zero.
