Answer:
1.137278672 m/s
+5.9 cm or -5.9 cm
Explanation:
A = Amplitude = 6.25 cm
m = Mass of object = 225 g
k = Spring constant = 74.5 N/m
Maximum speed is given by
The maximum speed of the object is 1.137278672 m/s
Velocity is at any instant is given by
The locations are +5.9 cm or -5.9 cm
Answer:
Time = 600 seconds
Explanation:
Given the following data;
Power = 60W
Energy = 36000
To find the time;
Energy = power * time
Substituting into the equation, we have;
36000 = 60 * time
Time = 36000/60
Time = 600 seconds.
Therefore, the bulb was on for 600 seconds.
Yes, of course, a good example would be us.

<h2>
Expalantion</h2>
In the ancient time, the scientists believed that there is the smallest particle which can control the nature of reaction in the environment which they called them. Then a lot of experiment was conducted in which new coming scientists discovered the protons, electrons, neutrons, and other smallest particles. Firstly, scientists performed experiments for this new discoveries to know better about them and then include them in their next experiment for better exposures.
K.E = 1/2mv^2
The kinetic energy is 50,000 J and the mass of the car is 10,000 kg.
50,000 J = 1/2(10,000kg)v^2
Solve for v (velocity)
50,000 J = 5,000 kg x v^2
10 = v^2
about 3 m/s (in terms of significant figures)
