21
350
130
Answer:
21
Explanation:
Weight on the moon is 16.5 % of weight on earth
Weight on moon = 0.165 * 130
Weight on moon = 21 lbs
Answer:
E.) None of the above
Explanation:
Draw a free body diagram. There are two forces acting on the car. Normal force perpendicular to the road, and weight downward.
Sum of the forces perpendicular to the road:
∑F = ma
N − mg cos θ = 0
N = mg cos θ
Sum of the forces towards the center of the circle:
∑F = ma
N sin θ = mv²/r
mg cos θ sin θ = mv²/r
g cos θ sin θ = v²/r
v = √(gr cos θ sin θ)
Given r = 50 m and θ = 5°:
v = √(9.8 m/s² × 50 m × cos 5° × sin 5°)
v = 6.52 m/s
v = 14.6 mph
