An experimental rocket sled weighs 5910 lb and is propelled by six rocket motors each with an impulse rating of 8120 Ib-sec. Therockets are fired one after the other at 1.2-sec intervals, and the duration of each rocket firing is 2.9 sec. If the velocity of the sled 11.8sec from the start is 165 mi/hr, determine the time average R of the total aerodynamic and mechanical resistance to motion. Neglectthe loss of mass due to exhausted fuel compared with the mass of the sled.RocketthrustAnswer: R =iIb

A torpedo was fired at a target ship by a submarine. The torpedo monitor of the target ship detects that 10 seconds pass between the moments when the explosion noise emitted by the water and air is heard. The torpedo travels in a linear orbit in the water. The propagation speed of sound in air is known as 340 m/s and the propagation velocity in water is 1430 m/s. Calculate the distance between the target ship and the torpedo accordingly.
In the system shown, a spring is compressed and pushes a mass of 50Kg down the path shown with two different slopes. If the spring has a constant of 25 kN / m, what would have to be the deflection of the spring for the block to reach the limit at 2 m / s? The coefficient of kinetic friction is 0.15 and assume that starting from rest to make the ideal system

A jogger with mass m = 55 kg uses energy at a rate of P = 802 W when she jogs on horizontal ground at a constant speed of s = 3.5 m/s. The efficiency of her “human engine” however, is e = 0.27. (In other words, the power used for locomotion is e = 0.27 times the total power.) Q) Write an expression for the rate of energy expenditure whenshe jogs at the same constant speed up a slope of 4.99 degrees. Assume whatever frictional or drag forces are the same in each case. Your answer should be in terms of the symbols given in the problem statement and g(9.80 m/s^2)
