The perimeter of rectangle ABCD is 256 inches. It's length is 3 times as long as its width. Find the area of triangle ABC.

Physics
A hydraulic jack is designed so that when the handle is pushed down 1 m, the piston raising the load moves up 0.015 m. IMA= 66.67 AMA= 26.67 Efficiency= 40% At this efficiency, what is the force required to lift a 5000 N weight?

physics
When a 1150 kg space rocket lifts off of ground. How many joules of energy has been provided by its engine during the time in which it achieves a speed of 180 m/s.

physics
use s=ut + 0.5*a*t^2 in vertical direction s =0 because there is no vertical displacement at the time it reaches the ground a= -9.81 ; minus because we consider up as the positive direction. u= 24.8 sin 62.5 ; vertical component of the Velocity SO t= 2*u/ -a = (2*24.8 sin 62.5...
