Chapter 11.4, Problem 49PPS

To determine

To convert speed of spacecraft, i.e., $35,800$ miles per hour to feet per second.

Answer to Problem 49PPS

Speed of spacecraft is $52,506.7$ feet per second

Explanation of Solution

Given:

Speed of spacecraft $=$ $35,800$ miles per hour

Formula Used:

  $1$ mile $=$ $5280$ foot

  $1$ hour $=$ $3600$ second

Calculation:

Given: Speed of spacecraft $=$ $35,800$ miles per hour

Using the above formula, we have:

Speed of spacecraft $=$ $35,800\times \frac{5280}{3600}$ feet per second

Solving further, we have:

Speed of spacecraft $=$ $52,506.67$ feet per second

Converting to the nearest tenth:

Speed of spacecraft $=$ $52,506.7$ feet per second

Conclusion:

Hence, Speed of spacecraft is $52,506.7$ feet per second
