Match the ESCAPE acronym with the concept each letter stands for. (The list of possible responses is long, so make sure to scroll down so that you can see everything.) Also, Blackboard won’t let me have two identical letters, so the last “E” has the second letter included as well.

What would be the weight of a 50.0 kg astronaut on the surface of a planet, which has a radius of 7.00 × 104 km and mass of 2.00 × 1027 kg?  G=6.67×10-11 Nm2/kg2.

Squid use jet propulsion for rapid escapes. A 5-kg squid can accelerate at 20 m/s2 by ejecting 0.3 kg of water. What is the magnitude of the thrust on the squid?

Consider the contour map of given below.  At point C, is [blank1]. At point C, is [blank2]. Let . At point C is [blank3]. At point A,  is [blank4].

A)  Find the directional derivative of at the point (1,2) in the direction of the vector

A) Find and equation of the tangent plane to the hyperboloid

Question: Answer the following question. LO 15c: What must be true about the coefficient of restitution for momentum and energy to be conserved during an impact? Explain your reasoning.

Problem: Use the figure below to answer the following question.  Assume Ball A has a mass of 0.2 kg while Ball B has a mass of 0.5 kg.  Ball A is initially moving with a velocity of 5 m/s to the right while Ball B is initially moving to the right at 2 m/s.  The coefficient of restitution is . LO 15c: What are the velocities of Ball A and Ball B just after the impact?  Show your work.  Describe the direction beyond a simple +/-. Value Solution Units Direction [sol] [units] [dir] [sol2] [units2] [dir2]

Problem: Use the figure below to answer the following question.  Assume Gear A is attached to a motor that starts at rest and before experiencing an angular acceleration of 3 rad/s2.   LO 16a: What is the angular velocity of Gear B at s?  Show your work.  Describe the direction beyond a simple +/-. Solution Units Direction [sol] [units] [dir]

Problem: Use the figure below to answer the following questions.  Assume the block weighs 8 N and the coefficient of kinetic friction between the block and the surface is
