a 15 kg dog jumps out of a 40 kg canoe if the dogs velocity is 1.2 m\s what is the velocity of the canoe?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
