Answer:
a=3.33m/s^2
Step-by-step explanation:
F=ma
a=F/m
To find Force you have to subtract the gravitational force by the air force
F=600-400
F=200N
m=60kg
Plug in the values:
a=200N/60kg
a=3.33m/s^2
Answer:
it d it because I took the test so that how I know
Answer:
A
Step-by-step explanation:
Factorise the numerator and denominator
w² - 9 = (w - 3)(w + 3) ← difference of squares
w² - 4w - 21 = (w - 7)(w + 3)
Hence the expression can be expressed as
Cancel the factor (w + 3) on the numerator/denominator. leaving
→ A
M = 25 - 31 / 3 - 4
m = - 16 / - 1
m = 16
25 = 16(3) + c
c = 25 - 48
c = - 23
y = 16x - 23
