A 5kg block was placed on an inclined plane(50 degrees with respect to the vertical).Forces A is at angle C with respect to the horizontal. Force B is parallel with the incline.The coefficients of static and kenetic friction are 0.3 and 0.2 respectively.
A=197KN
B=49 KN
C=7 degrees
A.Determine if there is motion and its direction
The block is initially 5m from the ground (vertically).Based on your answer in "A",if block will be moved 2m vertically from its original elevation (relative to the incline and depending on the direction of motion)in a span of 5 seconds.
B. How much work was done?
C. What is its initial potential energy?
D. What is its final potential energy?
E. Find the change in potential energy?
F. How much power was used?
A simple pendulum is found to vibrate 50 times with 200s. When 1.5m of its length is reduces to a certain length, it vibrates 50 times in 175s. Find the original length of the pendulum.

Looking from above, three ropes are tied to a 8.0-kg object being exerted as Indicated. What is the object’s acceleration?
A crate of mass 8.0kg requires 72J of energy to push it through a horizontal distance of 6.0m. Neglecting frictional force, calculate the magnitude of the applied force on the crate. (9 = 10ms2)
Arnold and Juju are 140 m apart. Arnold can run at a speed of 8 m/s while Juju can run at a speed of 6m/s. If the two boys run at the same instant, straight towards each other, when and where will they meet?
