A force of 40.0N is applied in the positive x-direction to a block of mass 7.15 kg, at rest on a frictionless surface. HINT (a) What is the block's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.) m/s2 (b) How fast is it going (in m/s) after 5.50 s? m/s

Problem 10: A horizontal force of magnitude F = 56.6 N pushes on a block of mass m = 6.89 kg. The block is on a frictionless incline that makes and angle 0 = 32 degrees with horizontal. F

An object of mass 5 kg is acted on by two forces F1 = 6 i N and  F2 = 7 j N. What is the magnitude of the net acceleration? Give your answer in m/s2 to 2 sf.  The magnitude must be a positive number.

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
