A 35.0−kg dolphin decelerates from 12.0 to 7.50 m/s in 2.30 s to join another dolphin in play. What average force was exerted to slow the first dolphin if it was moving horizontally? (The gravitational force is balanced by the buoyant force of the water. ) −80.0 N +75.0 N −68.5 N +90.0 N

A 60.0 kg skier starts from rest at the top of a ski slope 63.0 m high. (a) If friction forces do −10.9 kJ of work on her as she descends, how fast is she going at the bottom of the slope? (b) Now moving horizontally, the skier crosses a patch of soft snow where μk = 0.21. If the patch is 65.0 m wide and the average force of air resistance on the skier is 180 N, how fast is she going after crossing the patch? (c) The skier hits a snowdrift and penetrates 3.0 m into it before coming to a stop. What is the average force exerted on her by the snowdrift as it stops her?

A group of particles is traveling in a magnetic field of unknown magnitude and direction. You observe that a proton moving at 4.75 km/s in the +x direction experiences a force of 1.50×10−16 N in the +z direction, and an electron moving at 8.50 km/s in the +y direction experiences a force of 2.25×10−16 N in the +z direction. What is the direction of the magnetic field? (The direction is an angle measured counterclockwise from the positive x axis to the nearest 0.1 degrees) 50.0∘ 75.2∘ 94.8∘ 159.6∘ 230.0∘ 255.2∘ 274.8∘ 339.6∘

A toy submarine of mass m = 0.930 kg moves around a submerged circular track of radius R = 2.02 m. The submarine's engine provides a constant propulsion force of F = 4.98 N. When the sub is in motion, it is subject to a viscous drag force exerted by the water. This force is proportional to the sub's speed; the proportionality factor is C = 1.11 kg/s. Assuming it starts from rest at t = 0 s, the speed v(t) of the submarine at a later time t is given by v(t) = F/C(1−e−Ct/m) where e is the base of the natural logarithm. How much time has passed when the submarine's speed reaches 6.0×101% of its terminal value? What is the magnitude of the submarine's acceleration a at this time?
