Q. A 48 kg mass attached to a spring oscillates with amplitude of 2.2 m. The total mechanical energy of the system is 380 J. Find the position of the mass when its speed is 2m/s. newtons.
Q. A 8 kg box slides d = 4.2m down the frictionless ramp, after that collides with a spring whose spring constant is 250 N/m. angle is 30 degrees.
A 2.00×10-2- cube of ice at an initial temperature of -19 is placed in 0.670 of water at 44.0 in an insulated container of negligible mass.
what is the magnetic force per meter exerted by one bolt. After the first spring compresses a distance of 28.5 cm, the second spring acts with the first to increase the force as additional compression occurs as shown in the graph. The car comes to ..
A 362 g object is attached to a spring and executes simple harmonic motion with the period of 0.200 s. If the total energy of the system is 6.71 J.
A daredevil on the motorcycle leaves the end of a ramp with a speed of 36.0 m/s. If his speed is 34.20 m/s while he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance. In meters
What is the velocity of the rocket when it runs out of fuel.
Find out the rate of the wheel's rotation in revolutions per minute that will produce this effect.
At t=0 a grinding wheel has an angular velocity of 30.0 rad/s. It has a constant angular acceleration of 31.0 rad/s^2 until a circuit breaker trips at time t = 2.00 s. From then on, it turns through an angle 428 rad as it coasts to a stop at constant..
Find out the maximum altitude reached by the rocket.
If the far end of the iron rod is in an ice bath at 0°C, find the rate of heat transfer passing from the boiling water to the ice bath. Suppose there is no heat loss to the surrounding air.
