Question

A boat is being towed at the rate of 12 mi/hr. At the instant (t=0) that thetowing line is cast off, a man in the boat begins to row in the direction ofmotion, exerting a force of 20lb. If the combined weight oftheman and theboat is 480 lb and the resistance in lbs is equal to 1.75v, where v ismeasured in ft/s, find the speed of the boat after ½ min.

A train running at 108 km/hr is stopped with uniform retardation in 50 seconds by the application of the brakes. Find the acceleration and the distance covered before coming to rest.
When we think about air resistance, we can definitely predict or expect that the air resistance forces heavily rely on speed. Explain what exactly do you look forward to when it comes to that reliance, is it F ∝ v^2? is it F ∝ v? is it F ∝ 1v^2 or something completely different? Elaborate on why you predict this relationship
A motorboat maintained a constant speed of 13 miles per hour relative to the water in going 22 miles upstream and then returning. The total time for the trip was 6.5 hours. Use this information to find the speed of the current.
Uphill escape ramps are sometimes provided to the side of steep downhill highways for trucks with overheated brakes. For a simple 14 ∘ upward ramp, what length would be needed for a runaway truck traveling 160 km/h ? Note the large size of your calculated length. (If sand is used for the bed of the ramp, its length can be reduced by a factor of about 2.)
