Homework Statement
On some strange planet you find that a 9.2 kg object falls downward 27.4 meters in 6.2 seconds. What is the magnitude of the accleration due to gravity on this planet? How much does the object weigh on this planet? How much would it weigh back on earth?
Homework Equations
xf = xi +vit +1/2at^2
w= mg
The Attempt at a Solution
a. 27.4 m/ 6.2 s = 4.42 m/s
27.4 = 0 + 4.42 + 1/2 a 6.2^2
27.4 = 4.42 + 19.22a
a= 1.195 m/s^2
b. 1.195(9.2)
10.99 mg(?)
c. (1.195) (9.8 m/s)
= 11.62 mg(?)
I thought the units would be in mg for the weight, but it said my units were inapproriate as well.
