Two forces FA and FB are applied to an object whose mass is 5.05 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 0.625 m/s2. However, when FA points due east and Fg points due west, the acceleration
is 0.472 m/s2, due east. Find (a) the magnitude of FA and (b) the magnitude of FB

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s

What is the speed vfinal of the electron when it is 10.0 cm from charge 1?
