What will a spring scale read for the weight of a 75 kg woman in an elevator that moves upward with acceleration 0.30 g? w=?

Calculate the force of the Earths gravity on a spacecraft 12,800 km (2 earth radii) above the Earths surface if its mass is 1350 kg?

A 0.140 kg baseball traveling 39.0 m/s strikes the catchers mitt, which, in bringing the ball to rest, recoils backward 13cm. Question- What is the average force applied by the ball to the glove? *Sigma Force= mass*acceleration

What is the magnitude of the average force required to stop an 1500kig car in 8.0 s if the care is traveling at 95 km/h? Formula: Sigma F= ma *convert 95km/h to 26m/s Which kinematic equation do I use and for which variable do I use within the equation?
