A child in a boat throws a 5.85−kg package out horizontally with a speed of 10.0 m/s. Part A Calculate the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 27.0 kg and that of the boat is 40.0 kg. (Take the package's direction of motion as positive.)

A 79-kg fisherman in a 116-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.1 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown. (skip units)

In a research facility, a person lies on a horizontal platform which floats on a film of air. When the person's heart beats, it pushes a mass m of blood into the aorta with speed v, and the body and platform move in the opposite direction with speed V. Assume that the blood's speed is 45.0 cm/s. The mass of the person + platform is 54.0 kg. The platform moves 5.45×10−5 m in 0.160 s after one heartbeat. Calculate the mass (in g ) of blood that leaves the heart. Assume that the mass of blood is negligible compared with the total mass of the person, and the person + platform is initially at rest. (Also assume that the changes in velocity are instantaneous.) g

A scientist builds an apparatus to measure the charge to mass ratio of ions. An ion is first accelerated to a speed of 4.50×107 m/s. It then passes through a region of magnetic field, with a magnitude of 2.44×10−2 T, perpendicular to the ion's velocity. Because the ion is moving so fast, it is only in the presence of the magnetic field for 2.00×10−7 s. Upon exiting the magnetic field, the scientist measures that the ion was deflected a distance of 3.00 cm in a direction perpendicular to its initial velocity. (a) What is the ratio of the absolute value of the ion's charge to its mass (in C/kg )? Assume the velocity change is small, and that the component of the velocity along the ion's original direction does not change noticeably. |q| m = Cg (b) Suppose the scientist determines the ion is singly charged; that is, the magnitude of its charge is that of a proton. What is the mass of the ion (in kg)? kg
