Since energy is always conserved, you can solve problems involving energy transfer. Russell Wilson throws a football straight up into the air. If he throws the ball (with mass .45 kg) with a speed of 25 m/s and there is no air resistance, how high does the football go? Insert a picture of your work (or type it out).
a. Write out the formula for this problem. (2 pts) b. Plug in the values from this problem into the formula. (2 pts)
C. Solve the problem, writing out each step. (2 pts)
d. Correct answer (2 pt)
e. In the real world, there would be air resistance. How will this affect the height the ball reaches and WHY? (2 pts)

(just wanna double check) if you are able to help, i may give brainliest ​

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

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.

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