1.If the magnitude of the resultant force is to be 500 N directed along the positive y axis determine the magnitude of force F and its direction
2.A particle begins from s=0 and is traveling along a straight path at a velocity of v=(t^2-4t+3) m/s, where t is in seconds. Construct a v-t graph and an a-t graph at the time interval t=0 to t=4 s.
3.A flow of 28 m3s-1 occurs in an earth-lined canal having a base width of 3 m, side slopes of 1(vertical) to 2 (horizontal) and the Manning’s n value of 0.022. Calculate the critical depth and critical slope
