Two blocks made of different materials, connected by a thin cord, slide down a plane ramp inclined at an angle 32 degrees to the horizontal. The mass of block A is 7.4kg and block B is also 7.4kg. The coefficients of friction are uA=0.18 and uB=0.37.
A) Determine the acceleration of the blocks.
B) Determine the tension in the cord.
In coming to a stop, a car leaves skid marks 82m long on the highway. Assuming a deceleration of 6m/s2, estimate the speed of the car just before braking.
Two simple pendulums have length of 81-cm and 64-cm they are released from the same angular position at the same instant. After how much time would they both arrive at their initial position simultaneously.
