Answer:
He should have added 0 to 8 and multiplied 1 by 8
Step-by-step explanation:
Answer:
The top box in the middle, should be 15.
The bottom box on the left should be 1.5
The acceleration due to gravity on earth is g = 32.174 ft/s².
Therefore on Mars,
g = (2/3)*32.174 = 21.45 ft/s²
When an object falls from rest over a distance h, the final velocity, v, obeys the equation
v² = 2gh
or
v = √(2gh)
Therefore, given h = 15 ft, the impact velocity on Mars is
v = √(2*21.45*15) = 25.367 ft/s
The closest given answer is 25.3 ft/s
Answer: B) 25.3 ft/s
