Here is a simple example. The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothi...

use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis. xy=1, x=0, y=1, y=3

A rocket is launched straight up with constant acceleration. Four seconds after liftoff, a bolt falls off the side of the rocket. The bolt hits the ground 6.70s later. What was the rocket's acceleration? Express your answer with the appropriate units.

A Styrofoam ball has just been shot straight up. Air resistance is not negligible. Draw a free-body diagram. i only have two attempts left and im not sure what im doing wrong. is the direction of gravity(down) and drag (up) wrong?

In an electricity experiment, a 1.30g plastic ball is suspended on a 56.0cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force F⃗ elec on it, causing the ball to swing out to a 25.0∘ angle an...

Compressed air is used to fire a 50g ball vertically upward from a 0.60-m-tall tube. The air exerts an upward force of 3.0N on the ball as long as it is in the tube. How high does the ball go above the top of the tube?

Block B in the figure(Figure 1) rests on a surface for which the static and kinetic coefficients of friction are 0.65 and 0.40, respectively. The ropes are massless.What is the maximum mass of block A for which the system is in equilibrium? (Consider the...

What is the maximum speed of a 3.40g particle that oscillates between x =2.0mm and x =8.0mm in the figure? (Figure 1) Description of Figure: Parabola with the lowest point at (4,1) parabola starts at(2,5) and ends at (8,5) Y-axis is U(J) X-axis is x(mm)

A box of mass m and initial speed v0 slides distance d across a horizontal floor before coming to rest. Use work and energy to find an expression for the coefficient of kinetic friction.Express your answer in terms of the variables v0, d, and free fall ac...

What is the velocity of the simple harmonic motion problem? Position of the graph is y= .4*cos(2pi*1/3*x)+1.2 I need to find the velocity as well as the acceleration. I have worked through it and keep getting that the velocity is 0. I don't believe that i...

I forgot the questions. What is the magnitude of F⃗ elec? What is the tension in the string?

Never mind. i figured it out. the diagram didn't even come out right anyways. Tension(T)=mu_static(μ_s)* mass(m)* gravity(g) T=.65(20)(9.8)= 127.4 N T=m(g) 127.4=m(9.8) m=13 kg for block A

How exactly do you get those answers? Also, the program says those are not the right answers.
