A student wants to know how high into the air she can throw a baseball. She threw the baseball straight up and caught it in 4 seconds. How HIGH
did the baseball go? *
(please answer, i really don’t wanna fail)

The metric unit of electrical power is the watt volt ampere ohm

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.
