Question: Four things are considered constant when even modern physics came and with the help of these you can solve any problem in classical mechanics. Do you know what are these? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
A fan is running at 898 rpm when the power goes out. It makes 1,311 complete revolutions before it finally stops. What was the angular acceleration
A 1500kg wrecking ball hangs from a 20m -long cable. The ball is pulled back until the cable makes an angle of 17.0° with the vertical. By how much has the gravitational potential energy of the ball changed?
A model rocket is constructed with a motor that can provide a total impulse of 29.0 Ns. The mass of the rocket is 0.175 kilogram. Find the speed that this rocket achieves
An inductor with an inductance of 2.60H and a resistor with a resistance of 14.0ohms are connected to the terminals of a battery with an emf of 7.00V, obtain the initial rate of increase of current in circuit
