for a horizontal block spring system, the maximum displacement is 15cm. if k = 150N/m,
a) calculate the mass of the block
b) calculate maximum value of kinetic energy
c) calculate maximum value of elastic potential energy
d) calculate total energy
Which kind of research is Professor Carter employing.
At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.50 s. From then on, the wheel turns during an angle of 440 rad as it coasts to a..
define the magnitude of the acceleration of the elevator. A 300 kg piano slides 4.1m down a 30 degree incline and is kept from accelerating by the man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction ..
Three light bulbs each with a resistance of 50W, are connected in series to a 100 V power supply. What is the current flowing through the third light bulb.
Find out an angular momentum of the system
The barrel has a length of 0.60 m and an opening whose radius is 2.8 10-3 m. A bullet (mass = 2.7 10-3 kg) has a speed of 380 m/s after passing through this barrel. Ignore friction and examine the average pressure of the expanding gas.
An airplane can be made invisible to radar by coating the plane with a thin layer of an antireflective material. If radar waves have a wavelength of 3.0 cm.
On the floor1.5 m in front of the mirror is a small table, 0.75 mhigh. Illustrate what is the minimum height the mirror must have foryou to be able to see the top of the table in themirror?
Suppose the solenoid filled with a paramagnetic substance such as liquid oxygen. Qualitatively,how will this change your your answer to Part (b)? Will your reply increase, decrease,or remain the same.
A car of mass = 800 travelling at 45.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and the car's tires. What is the radius of the turn if = 20.0 (Assume the car continues in unif..
A 238 g particle is released from rest at point A inside a smooth hemispherical bowl of radius 32.5 cm.compute the gravitational potential energy at A relative to B.
A typical power plant uses some fuel as the source of heat (QH) to drive a heat engine that does work (W) to drive a generator that is connected to the electrical grid. Inevitably, waste heat (QC) is dumped into a river or lake. Analysis of the pl..
