The mass of the stepped disk is 18 kg and its moment of inertia is 0.28 kg-m2. If the disk is released from rest, what is its angular velocity when the center of the disk has fallen 1 m?

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.

Asher cycles 12 miles in 16 hours. what is his speed?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
