Answer:
A. 26.17 B. 1.17 C. 30.86 D. 5.86
Explanation:
Answer:
7.6 s
Explanation:
Considering kinematics formula for final velocity as

Where v and u are final and initial velocities, a is acceleration and s is distance moved.
Making v the subject then

Substituting 8.8 m/s for u, 138 m for s and 2.45 m/s2 for a then

Also, v=u+at and making t the subject of the formula

Substituting 27.45 m/s for v, 8.8 m/s for u and 2.45 m/s for a then

Therefore, it needs 7.6 seconds to travel
Explanation:
Since I can only do this by observation, the elevation of F is approximately 850km and the elevation of B is 925km.
