Question 1 of 50 Jason has 13720 J of gravitational potential energy standing at the top of a diff over the lake. After he jumps off the diff how fast does he enter the water? Jason has a mass of 75 kg.
A. 19 m/s
B. 366 m/s
C. 1400 m/s
D. 37 m/s

Aparticle travels in a circular orbit of radius 21 m. its speed is changing at a rate of 23.1 m/s2 at an instant when its speed is 37.2 m/s. what is the magnitude of the acceleration (in m/s? ) of the particle?

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
