Object 1 has a mass m1 and a velocity v? 1 = (2.40m/s )x^. object 2 has a mass m2 and a velocity v? 2= (3.30m/s )y^. the total momentum of these two objects has a magnitude of 19.0kg? m/s and points in a direction 70.0? above the positive x axis. find m1 and m2

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
