A rocket takes off from Earth's surface, accelerating straight up at 43.2 m/s2. Calculate the normal force (in N) acting on an astronaut of mass 81.9 kg, including her space suit. (Assume the rocket's initial motion parallel to the +y-direction. Indicate the direction with the sign of your answer.)

[10] (2) Consider a rocket traveling in a straight-line subject to an external force Fext acting along the same line. The equation of motion is my =-mvex + Fext where (-mvex) is the thrust. [4] (2.a) Specialize to the case of a rocket taking off vertically (from rest; and positive y is upward) in a gravitational field g, so the only external force is the weight mg. Assume that the rocket ejects mass at a constant rate, m=-k (where k...
.Please form info discussion groups of 3 (no more than 3) to solve the following questions. Use the boards in the classroom to discuss the details of your solutions and show of work. Markers and erasers will be provided. Please return them after end of the class. Groups will be called to solve the questions for the rest of the class (bonus points opportunity) The final answers to each question is provided in the parenthesis. You need to arrive at...
Question 2 According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: Question 2 options: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on...
don a sled starts from rest at the top of a 15.0° slope. If the trip to the bottom takes 2 s, how long i A) 586 mB) 293 m C) 1130 m D) 147 m 2) Two children fighting over a toy pull on the toy in different directions. One child pulls to the north with a force of 5.3 N, and the other child pulls to the east with a force of 6.3 N. What is the magnitude...
