A mass of 0.75 kg is attached to a spring and placed on a horizontal surface.
The spring has a spring constant of 180 N/m, and the spring is compressed
0.3 m past its natural length. If the mass is released from this compressed
position, what is the speed of the mass as it passes the natural length of the
spring?

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.
