Answer #1

Solution:

The problem mentions a expotentially decreasing force. However no figure is given regarding the application of the force on the cart. Therefore I have to assume the standard exponential function and have solved accordingly. If the application of force differed from what is taken in the solution. please mention the specifics in the comment section and I will be happy to reflect them in my solution. Now lets get back to the solution.

A mass m is at rest on a horizontal frictionless surface at t=0. Then a constant force F0 acts on it for a time t0. Suddenly the force doubles to 2F0 and remains constant until t=2t0. Determine the total distance traveled from t=0 to t=2t0, in terms of the variables m, F0, t0, and appropriate constants.

a)A 0.05 kg mass is used to accelerate a cart. At t=1 second, the 0.5 kg cart is at x=0.5 m, at rest. At t=2.5 seconds, the cart is at 1.5 m, traveling at 1.3 ± 0.3 m/s. Calculate and compare the impulse with the total change in momentum of the cart and mass. (Read the theory and sections 1.5 through 1.7 if you’re not sure how to do this.) b) What would be the effect of air resistance and...

The diagram below shows a block of mass m=2.00kgm=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and F3=8.00NF3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...
