A 2.2×104 kg rocket has a rocket motor that generates 2.7×105 N of thrust. Part A What is the rocket's initial upward acceleration? Express your answer with the appropriate units. Part B At an altitude of 5000 m the rocket's acceleration has increased to 7.5 m/s². What mass of fuel has it burned? Express your answer with the appropriate units.

Please use at least 4 significant figures throughout the entire problem! Also use 9.80m/s2 for the acceleration due to gravity. DO NOT USE 10 M/S2 FOR THE ACCELERATION DUE TO GRAVITY! Thank You.

A cardboard box rests on the floor of an elevator. The box has a mass m = 2.75 kg and the elevator has an upward acceleration of a.   a.  Write an expression for the sum of the forces acting on the box in the y-direction, ΣFy, given that up is the positive y-direction. Your answer should be in terms of FN, m, and g.  b. Write an expression for the normal force, FN, that the block experiences in terms of the elevator's acceleration, the block's mass, and the acceleration of gravity.  c.  If the elevator's acceleration has a magnitude of g in the downward direction, what would the normal force, FN1 be in Newtons?  d.If the elevator's acceleration had a magnitude of g in the upward direction, what would the normal force FN2 be in Newtons?

A spacecraft was designed to assess the ability of an impact to deflect the path of an asteroid. The spacecraft was launched on a rocket. At launch, the rocket has a mass of 555,000 kg and generates a force of 7.6 x 106 N. A. If you were to neglect the effect of gravity, what would the intial acceleration of the rocket be? B. If the acceleration were to remain constant, how fast will the rocket be moving after two seconds? C. As the rocket burns fuel its mass decreases. If the thrust remains the same, how would your answer to part B change? Would the speed after two seconds be lower, the same or higher?

A teenager of mass m1 = 56 kg pushes backwards against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude F foot = = 18.5 N. The skateboard has m2 = 2.6 kg. a. Write an expression for the magnitude of the horizontal component of force that the ground exerts on the teenagers foot, F ground. b. Write an expression in terms to given quantities for the magnitude of the skateboard acceleration, a , while the teenager is pushing backwards on the ground? c. What is the numerical value of the magnitude of the acceleration, a, in m/s square?
