Answer:
Is the equation for Ec=1/2 m(Dv)^2 where Dv is the difference between the angular speed & the areolar speed?
The net force needed to accelerate a 200 kg piano is 50N
According to Newton's law of motion, the formula for the net force is calculated as:
∑F = ma
Given the following parameters
Mass = 200kg
acceleration = 0.25m/s²
Substitute the given parameters into the formula
∑F = 200 * 0.25
∑F = 50N
Hence the net force needed to accelerate a 200 kg piano is 50N

Answer:
Option B. The distance between the objects in Figure A is shorter than the distance between the objects in Figure B.
Explanation:
The force of attraction between two masses is given by the following equation:
F = GM₁M₂ / r²
Where:
F => is the force of attraction
M₁ and M₂ => are the masses of the two objects
G => is the gravitational constant.
r => is the distance between the two objects
From the above formula,
The force of attraction (F) is directly proportional to the product of the two masses and inversely proportional to the square of their apart.
This implies that:
1. An increase in the masses of the object will bring about an increase in the force of attraction and a decrease in the masses will leads to a decrease in the force of attraction.
2. An increase in the distance between the two masses will leads to a decrease in the force of attraction and a decrease in the distance between the two masses will lead to an increase in the force of attraction.
Considering the options given in the question above, option B gives the correct answer to the question.
Time= v*sintheta/g = 10*1/9.8= 1.02s therefore h=1/2*9.8*(1.02)^2= 5.10m
