Answer:
Though no question is specified here but let analyzed experiences of each
Explanation:
1. Required a force to stop it (Law of inertial). Constant acceleration
2. will have reduced acceleration (deceleration)
3. Uniform acceleration may set in. it accelerate
4. maximized it speed since no friction affect it motion
5. accelerating. Vo=0 and V gradually increased
6. less or no friction opposes the motion
7. It experience reduce motion based on air friction
8. constant acceleration due to gravity
9. g can be a bit affected but still about equal
Answer:
Yes it is balanced
Explanation:
Because 10-10= a net force of 0N
Its equal (balanced)
Answer:
34 m/s
Explanation:
Potential energy at top = kinetic energy at bottom + work done by friction
PE = KE + W
mgh = ½ mv² + Fd
mg (d sin θ) = ½ mv² + Fd
Solving for v:
½ mv² = mg (d sin θ) − Fd
mv² = 2mg (d sin θ) − 2Fd
v² = 2g (d sin θ) − 2Fd/m
v = √(2g (d sin θ) − 2Fd/m)
Given g = 9.8 m/s², d = 150 m, θ = 28°, F = 50 N, and m = 65 kg:
v = √(2 (9.8 m/s²) (150 m sin 28°) − 2 (50 N) (150 m) / (65 kg))
v = 33.9 m/s
Rounded to two significant figures, her velocity at the bottom of the hill is 34 m/s.
They do not demonstrate Earth's tilt. In fact, they're not "used" to demonstrate anything. It works the other way:. When you observe the Coriolis effect and the behavior of the Foucault pendulum, and you try to explain why the behave the way they do, one possible simple explanation for both of them is the Earth's ROTATION. Then, when you also observe the rising and setting of the sun and moon, and you also notice how the NUMBERS all go together, the case for the rotating, spherical Earth gets stronger and stronger.
Answer:
Wait, that can happen? I'm sorry.
