To calculate the normal and tangential components of the
acceleration of an object along a given path.
A particle is traveling along the path y(x)=0.2x2y(x)=0.2x2, as
shown in (Figure 1), where yy is in meters when xx is in meters.
When xxx = 7 mm , the particle's velocity is vvv = 10 m/sm/s and
the magnitude of its acceleration is aaam = 4 m/s2m/s2 . Determine
the normal and tangential components of the acceleration.

A 250 g block is moving along the “x” axis and at some point a
force in the positive direction of the axis acts on it.
The graph shows the magnitude of the force versus the position
“x” of the particle. The curve is given by F=a/x^2, with a=9.0 N.m2
. Find the work done on the block by the force as the block moves
from x=1.0 m to x=3.0 m by:
a.) Estimating the work from the graph.

Instructions: 1. Draw the schematic of the situation described in the wording of the problem. This schematic includes a list of the data given in the wording of the problem, such as initial position (x, yo), initial velocity Ivo, V, Vol, final position (x,y), final velocity (V, V, W) or maximum height (ym). Make a decision on whether you want to use "y" or "h" for the vertical axis and keep it consistent throughout all the problems. Write down the...

Imagine a 4.0-kg wood block sliding across a horizontal table surface with a positive velocity and an acceleration of -2.0 m/s. You need to calculate the coefficient of kinetic friction for these two surfaces. 1. Start the same way you always should whenever you have a question involving forces and accelerations. Draw a free-body diagram (arrows for all the forces, arrow for net force, and a coordinate system) for the block. All the forces, vertical as well as horizontal. 2....
