What is the magnitude of the resultant force (caused by the other two masses) on the mass at the origin? the universal gravitational constant is 6.6726 × 10−11 n · m2 /kg2 . answer in units of n.

An uplifted block of rock between two normal faults

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
