Kinetic energy of the sled
A 8 kg sled is initially at rest on a horizontal road. The sled is pulled a distance of 3.2 m by a force of 36 N applied to the sled at an angle of 30o to the horizontal. Find the change in the kinetic energy of the sled.

Think of the beaver's digestive organ system. Explain its overall role. List several of the organs in this system, describe how each functions, and outline how the organs work together to carry out the role of the organ system.
Will the gravitational potential energy increase, decrease, or stay the same?assume a density for the region before collapse, although your estimate will be uncertain by a factor of order unity. Does your answer make sense compared to the age of t
Plot the function y = 10(1-e^(-x/4)) over the interval 0<=x<=xmax, using a while loop to determine the value of xmax such that y(xmax)=9.8. Properly label the plot. The variable y represents force in newtons, and the variable x represents time
