The figure shows an unlabeled force diagram for a moving object that is missing one force. The length of the sides of the square grid corresponds to a force magnitude of 1 N.  1) Which additional force has to be exerted on the object so that the object accelerates downwards. Choose all answers that are correct. 2) Which additional force has to be exerted on the object so that the object moves at a constant speed. Choose all answers that are correct.

A diagram represents a cart moving on a ramp. Assuming a frictional force of 12.2N. what is the magnitude of the net force acting on the cart.

A micro-transporter moves from one side of an evacuated chamber to another. It is powered by equal-magnitude, opposite-sign charges Q and -Q on top of two station points, as shown in (Figure 1). The transporter's mass is 1.0 g and it is carrying a positive charge of 9.0 x 10-10 C. The figure shows a micro-transporter located between two stations on a horizontal surface. Figure The left station has charge plus upper Q. The right station has charge minus upper Q. The transporter carries positive charge q. The transporter is 6.0 millimeters from the left station and 36.0 millimeters from the right station. +Q Station ( + Station 6.0 mm 36.0 mm

A stockroom worker pushes a box with mass 12.9 kg on a horizontal surface with a constant speed of 2.50 m/s. The coefficients of kinetic and static friction between the box and the surface are 0.340 and 0.470, respectively.
