QUESTIONI (a). Suppose an object is weighed with a spring
balance, first in air and then whilst totally
immersed in water. The readings on the balance
are 0.48 N and 0.36 N respectively. Calculate the
density of the object.​

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.
