y is the vertical height of the launcher (above the floor), and vo is the launch speed of the ball. As shown, the ball launched completely horizontally. If y = 1.33 m, and vo= 5.7 m/s, what is the horizontal range of the ball (that is, how far does it travel in the x-direction before hitting the ground)?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
