Question

46. A plane passes over Point A with a velocity of 8000 m/s north. Forty seconds later it passes
over Point B at a velocity of 10,000 m/s north. What is the planes' acceleration from A to B?
a. - 50 m/s/s north
b.-200 m/s/s north
c. 50 m/s/s north
d. 200 m/s/s north​

Answer 2

Answer:

C. 50 m/s/s, north

Explanation:

Acceleration= ( V - Vo) / T

V = Final Velocity

Vo = Initial Velocity

T = Time

Solution:

a = ( V - Vo ) / T

a = ( 10000 m/s - 8000 m/s) / (40 s)

a = 2000 m/s/s / 40 s

a = 50 m/s/s
