Answer:
v = 46.5 m/s
Explanation:
Given data:
Mass of car = 1210 kg
Momentum of car = 56250 kg m/s
Velocity of car = ?
Solution:
Formula:
p = mv
p = momentum
m = mass
v = velocity
Now we will put values in formula:
56250 kg m/s = 1210 kg × v
v = 56250 kg m/s / 1210 kg
v = 46.5 m/s
So a car having mass of 1210 kg with momentum 56250 kg m/s having 46.5 m/s velocity.
In the pot of tea the molecules would be moving faster than in the cooled cup of tea. As liquid is heated the atoms vibrate faster which increases the distance between them. When heat leaves a substance, the molecules vibrate slower and get closer.
When Water freezes or begin to freeze, it molecules start to slow down enough that their attraction arrange into one shape till they melt again.
