11. A ball is thrown up and attains maximum height of 20 m. Calculate its initial speed. (g = 10 ms') a) 19.7 m/s
b) 20 m/s
c) 25 m/s
d) 35m/s

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

Which word expression describes how much to calculate pressure

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
