If the bob's mass is increased by a factor of 4, approximately what will the pendulum's new period be

Avalue that describes how heavy an object is and is related to the force of gravity is

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.

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is
