Two trucks with equal mass are attracted to each other with a gravitational force of 6.7'10-4 n. the trucks are separated by a
distance of 3.0 m. what is the mass of one of the trucks? (g=6.673' 10-11 nm2/kg)

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

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)
