A football player kicks a field goal from a distance of 45 m from the goalpost.
The football is launched at a 35° angle above the horizontal.
What initial velocity is needed so that the football just clears the goalpost crossbar that is 3.1 m above the ground?
Ignore air resistance and the dimensions of the football
The weightless simply supported beam below has a VDL of P61kN/m, a point load of P62 kN and a UDL of P63 kN/m as shown. Determine the vertical reaction force at A the maximum bend
Q. Find the electric potential at a distance 0.09 m from a charge of 4 X 10 -7 C. The electric potential V = ( 1/4πεo ) q /r = ( 9 X 10 9 X 4 X 10 -7 )/ 9 X 10 -2 = 4 X 10

When a liquid moves by a pipe having a varying diameter, the pressure against the inside walls of the pipe will be: a) The same throughout b) Lowest where the diameter is
Explain Motion in 2 Dimensions When motion occurs in two dimensions, position, displacement and distance, speed, velocity and acceleration can be described using the x-y plane.
Moment, Centre of mass and Centroid Moment of force is tendency of the force to twist or rotate an object. A measure of the body's resistance to the angular acceleration, which
