Calculate the force necessary to accelerate a 20,000-lbm rocket vertically upward at a rate of 100 ft/sec^2. Assume g 32.2 ft/sec 2
help me about this pleasee
1. Determine the upward applied force, in lbf, required to accelerate a 2,04 kg model rocket vertically upward. with an acceleration of 3 g's. The only other significant force acting on the rocket is gravity, and I g9,8 m/s2. 2. Figure 2 shows an object whose mass is 5 lb attached to a rope wound around a pulley. The radius of the pulley is 3 in. If the mass falls at a constant velocity of...

[NMIDPDIACJ] Will Ferrell's water rocket of mass 5.85 x 102 g accelerates vertically upward at 26.0 m/s2 during launch, overcoming both gravity and air resistance. (a) Draw a free-body diagram of the rocket during launch once it has departed from the launch pad. (b) Calculate the thrust force applied by the rocket engine during launch if the air resistance acting on the rocket is 0.95 N.
A small rocket having an initial weight of 3000 lb (including 2400 lb of fuel), and initially at rest, is launched vertically upward. The rocket burns fuel at a constant rate of 80 lbs, which provides a constant thrust, T, of 8000 lb. The instantaneous weight of the rocket is w(t) = 3000 - 80t lb. The drag force, D, experienced by the rocket is given by D = 0.005g(dy/dt)^2 lb, where y is distance in ft, and g =...

Question 3 (1 point) A model rocket of mass 4.80 x 102 g accelerates vertically upward at 34.0 m/s2 during launch, overcoming both gravity and air resistance. [KMINJU] a. Draw a free-body diagram of the rocket during launch once it has departed from the launch pad. b. Calculate the thrust force applied by the rocket engine during launch if the air resistance acting on the rocket is 2.40 N.

f A model rocket is fired vertically upward from rest. Its acceleration for the first three seconds is atet) sat, at which time the fuel is exhausted and it becomes a nds later, the rocket's parachute opens, and the (downward) velocity slows inearty to-13 n/s in S s. The rocket then "hets" to the ground at that rate freely "Talling" body. Thirteer (a) Determine the position function s and the velocity function v (for all...
2. Your 300 kg rocket car gets a constant force from its rocket to accelerate it at 4 m/s for 10 seconds. How much energy is transferred by work in this process? Neglect friction from wheels and air resistance. Answer in kJ. Answer: less than 250. Hint: there is more than one valid approach to calculate the energy transfer in this problem. One is much easier than the other.
