Neat and clean solution Problem 7-10: Formulate DE for problems involving Newton's Secondo Law of Motion.7. A boat is towed at the rate of 12mi/hr. Att = 0, the towing line is cast offand a man in the boat begins to rowin the direction of motion exerting force of 20 lb. The combined weight of the man and the boat is 480lb. Thewater resists the motion with a force equal to 1.7v Ib, where v is the velocity of the boat in feet per second.Derive a DE leading the velocity of the boat.

Problem No. 1 (Kinetics: Rectilinear Motion) Block B rests upon a smooth surface. If the coefficients of static and kinetic friction between A and B are μs = 0.4 and μk = 0.3,respectively, determine the acceleration of each block if P = 6 lb.
The wooden block (mass m = 0.5358 kg) is released from rest at A by a compressed spring (compressed length 0.6 m, undeformed length 1 m, spring constant k = 150 N/m). The block is allowed to slide through the rough horizontal surface (A to B), then along the smooth circular ramp (B to C, central angle θ = 47.2°, until the block is released after point C. Calculate the speed of the block at points B and C. Also, what is the magnitude of the normal force exerted to the block just before the block leaves the ramp? Neglect the geometry of the block.NOTE: Use Work-Energy Method to solve for the speeds; use Force-Mass-Acceleration (FMA) Method to compute for the normal force.
