To convert from newtons to kg in earth gravity, simply divide by 10 (or 9.8 if being specific). 645N = ~64.5kg
Answer:
1 m/s
Explanation:
2 to 3 second interval would be zero.
3 to 4 is 2 m/s
so average is 1 m/s
Answer:
C
Explanation:
Givens
m = 2 kg
F = 2 * 9.81
F = 19.62 N
x = 0.15 m
Formula
F = k*x
Solution
19.62 = k*0.15
k = 19.62/0.15
k = 130.8 which rounded to the nearest given answer is C
