A block with mass m = 5.00kg slides down a surface inclined 36.9 ? to the horizontal (the figure (Figure 1) ). The coefficient of kinetic friction is 0.27. A string attached to the block is wrapped around a flywheel on a fixed axis at O. The flywheel has mass 29.0kg and moment of inertia 0.500 kg?m2 with respect to the axis of rotation. The string pulls without slipping at a perpendicular distance of 0.400m from that axis.
1. What is the acceleration of the block down the plane?
2. What is the tension in the string?
A drinking straw 20 cm long and 3 mm in diameter stands vertically in a cup of juice 8.0cm in diameter. A section of straw 6.5cm long extends above the juice. A child sucks on the straw, and the level of juice in the glass begins dropping at 0.23c..
A 2 g lead (cp = 128 J/kg•°C) bullet travelling at 325m/s is stopped by the large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet whereas the other half is transmitted to the tree, wha..

Thus, to eliminate the difficulties with motion sickness, designers must choose the distance between the astronaut's feet and the axis about which the space station rotates to be greater than a certain least value. What is this least value.
The wire is cut at point P. Will the potential difference between points A and B increase, decrease, or remain the same? Give reason for.
The electric potential difference between two infinite, parallel metal plates is V. If the plates are separated by a distance L = 4.50 mm and the electric field between plates is E = 270 V/m, what is V.
