Question: An ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min.
a. What is its angular acceleration in rad/s2?.
b. What is the tangential acceleration (in m/s2) of a point 10.00 cm from the axis of rotation?
c. What is the radial acceleration in m/s2? and in multiples of g of this point at full rpm?
The velocity of a ball changes from ‹ 9, ?7, 0 › m/s to ‹ 8.96, ?7.14, 0 › m/s in 0.02 s, What is the rate of change of momentum of the ball
A heat engine extracts 50.0kJ of heat from the hot reservoir each cycle and exhausts 35.0kJ of heat. What is the thermal efficiency
two stationary positive point charges charge 1 of magnitude 3.15nc and charge 2 of magnitude 1.75nc are separated by a
Consider a double-slit experiment with narrow slits, you use a screen placed far from the slits to detect the interference pattern. We now add a material in front of just one of the slits so that the light ray is shifted 180° out of phase just bef..
A 35 g bullet moving at 475 m/s strikes a 4.20 kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 270 m/s. How fast is the bag moving when the bullet exits.
A hot- air balloon is ascending at the rate of 12m/s and is 80 m above the ground when a package is dropped over the side. (a) How long does the package take to reach the ground? (b) With what speed does it hit the ground?
The tires of a 1465 kilogram car are 0.603 meter in diameter and the coefficients of friction with the road surface are µs = 0.800 and µk = 0.600. Find the maximum torque that can be exerted by the engine on a driving wheel without spinning the w..
Two masses are on a frictionless horizontal surface moving by 2 perpendicular directions (m1=m & m2=3m). After the collision the m1 mass stops. What is the velocity of mass m2 after the collision, if before the collision of the masses v1=5m/s and v2=..
The earth has a vertical electric field at the surface,pointing down, that averages 102 N/C. This field is maintained by various atmosphericprocesses.
