Answer:
1) k = 52 N/m
2) E = 1.0 J
3) ω = 8.1 rad/s
4) v = 1.4 m/s
Though asked for a velocity, we can only supply magnitude (speed) because we don't have enough information to determine direction.
If it happens to be the first time it is at y = - 10 cm after release, the velocity is upward.
Explanation:
Assuming the initial setup is after all transients are eliminated.
kx = mg
k = mg/x = 0.8(9.8) / 0.15
k = 52.26666.... ≈ 52 N/m
E = ½kA² = ½(52)(0.20²) = 1.045333... ≈ 1.0 J
ω = √(k/m) = √(52 / 0.8) = 8.0829... ≈ 8.1 rad/s
½mv² = ½kA² - ½kx²
v = √(k(A² - x²)/m) = √(52(0.20² - 0.10²)/0.8) = 1.39999... ≈ 1.4 m/s
Answer:
Newton's insight on the inverse-square property of gravitational force was from intuition about the motion of the earth and the moon. The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G .

Answer:
The speed of the car after the break was applied is 90.46 m/s
Explanation:
Given;
initial velocity of the car, u = 26.8 m/s
accelertation of the car, a = -8.2 m/s²
time of motion, t = 14.3 s
final velocity, v = ?
Apply the following kinematic equation;
v = u + at
v = 26.8 + (-8.2 x 14.3)
v = 26.8 - 117.26
v = -90.46 m/s
magnitude of the final velocity = 90.46 m/s
Therefore, the speed of the car after the break was applied is 90.46 m/s
Explanation:
In a manual transmission there are three pedals. From left to right, they are: Clutch, Brake, Gas. The clutch is the only pedal you press with your left foot. The other pedals – brake and gas – operate just like they do in an automatic transmission.
