The diagram shows the all of the forces acting on a body of mass m = 7.95 kg. the three forces have magnitudes f1 = 12.8 n, f2 = 29.3 n, and f3 = 13.3 n, with directions as indicted in the diagram, where θ = 28.8 degrees and the dashed line is parallel to the y axis write an expression for the x component of the acceleration in terms of the symbols in the problem statement

Why does the input force have to be greater than the force needed to lift the bale?

The gun from the crime scene shows tool marks where the serial numbers are ground off. there are also tool marks on the bullets left behind. what information can the tool marks on the bullets and gun provide about the crime? what type of evidence does this information provide, individual or class?

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
