Concept explainers
The gravitational differences between the earth and Mars is a factor that engineers and scientists must consider before sending an astronaut to the “Red Planet." (a) What is the acceleration due to gravity on Mars? (b) If an 85.0-kg astronaut landed on Mars, how much would the astronaut weigh there compared to his weight on the earth? (c) Based on the acceleration due to gravity on Mars, what might happen to the strength of the astronaut's muscles while the astronaut is away from earth?

- You're on an interplanetary mission, in an orbit around the Sun. Suppose you make a maneuver that brings your perihelion in closer to the Sun but leaves your aphelion unchanged. Then you must have Question 2 options: sped up at perihelion sped up at aphelion slowed down at perihelion slowed down at aphelionarrow_forwardThe force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees.
