Force = mass * acceleration
mass = Force/acceleration
= 36/2
mass = 18 kg
Answer:
Decreasing in altitude and increasing in velocity
Explanation:
The formula for potential energy is:

where m is mass, g is constant gravitational energy and h is the potential altitude.
The formula for kinetic energy is:

where v is the velocity
Since m,g are constant, to convert from potential energy to kinetic energy, h must decreases while v increases. For example dropping an object from a height.
Answer:
12mph in 2hrs and 3mph in 0.5hrs the total distance would be 12*2 and 3*0.5 which would be 24 and 1.5 so we add those 24+1.5= 25.5. The answer would be 25.5
Micah knows that a car had a change in velocity of 15 m/s.To determine acceleration ,Micah also needs the TIME of the total trip in seconds.
Explanation:
Solution,
Volume (v)=287 cm^3
Mass(m)=816 g
Density(d)=m/v
=816/287
=2.84
So, the density of the block of marbles is 2.84 g/cm^3.
