(3 points) two forces (f1x = 4.4 n; f1y = 2.1 n) and (f2x = 9.3 n; f2y = −3.8 n) act on an object of mass m = 9.4 kg. the mass is initially at rest. what is the kinetic energy of the mass after 2.6 s?

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
