The surfaces between a 7 kg block, the 23 kg wedge and between the 23 kg wedge and the horizontal plane are smooth (without friction). the acceleration of gravity is 9.8 m/s 2 . a block is released on the inclined plane (top side of the wedge). 7 kg 29◦ 23 kg 9 f .8 m /s^2. what is the force f which must be exerted on the 23 kg block in order that the 7 kg block does not move up or down the plane? answer in units of n.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
