Janet was bored last Saturday and so decided to build a massive catapult to occupy herself during quarantine (see image below). If her catapult launches her in the air with an initial velocity of +15.3 m/s, what is her velocity after she’s travelled 11.9 m above the catapult?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
