You serve a volleyball with a mass of 2 kg. The ball leaves your hand with a speed of 30 m/s. What is the KE of the ball? find the product

KE= 900joules, product= 60kgm/s momentum

Explanation:

KE=1/2MV2= 1/2× 2×30×30=900J

PRODUCT= MOMENTUM= 30m/s×2kg= 60kgm/s

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
