Question
Chapter 2, Problem 34P
To determine
The time taken by the car to attain the given speed.
Expert Solution & Answer
Answer to Problem 34P
2.4 seconds.
Explanation of Solution
Given:
Initial velocity of the car =vi=0ms
Final velocity of the car =vf=85kmh=85(1000m3600s)=23.6ms
Acceleration experienced by the car during free fall =a=g=9.8ms2
Time taken =t
Formula Used:
Acceleration is given as
a=vf−vit
Calculation:
Substituting the values,
9.8=23.6−0tt=23.69.8t=2.4sec
Conclusion:
Therefore, time taken by the car is 2.4 seconds.

- You are in the early stages of an internship at NASA. Your supervisor has asked you to analyze emergency procedures for extravehicular activity (EVA), when the astronauts leave the International Space Station (ISS) to do repairs to its exterior or perform other tasks. In particular, the scenario you are studying is a failure of the manned-maneuvering unit (MMU), which is a nitrogen-propelled backpack that attaches to the astronaut's primary life support system (PLSS). In this scenario, the astronaut is floating directly away from the ISS and cannot use the failed MMU to get back. Therefore, the emergency plan is to take off the MMU and throw it in a direction directly away from the ISS, an action that will hopefully cause the astronaut to reverse direction and float back to the station. You have the following mass data provided to you: astronaut: 78.1 kg, spacesuit: 36.8 kg, MMU: 115 kg, PLSS: 145 kg.
