Answer:
d=0.137 m ⇒13.7 cm
Explanation:
Given data
m (Mass)=3.0 kg
α(incline) =34°
Spring Constant (force constant)=120 N/m
d (distance)=?
Solution
F=mg
F=(3.0)(9.8)
F=29.4 N
As we also know that
Force parallel to the incline=FSinα
F=29.4×Sin(34)
F=16.44 N
d(distance)=F/Spring Constant
d(distance)=16.44/120
d(distance)=0.137 m ⇒13.7 cm

Answer:
plug it into your calculator
Explanation:
Kinetic energy = KE = Joules = J
KE= 1/2mv^2
90,000 = 1/2 m (12^2)
180,000 = m (144)
m = 180,000 / 144
