air beomes more dense
below dewpoint = a dew forms ... wet underfoot.
cold enough = frost ???
Answer:
5437.5 N
Explanation:
from the question we are given the following:
mass = 7.25 kg
initial speed (u) = 10.5 
finial velocity (v) = 0
compression (s) = -7.35 cm = -0.0735 m (the negative sign is because the face is compressed, so there is a decrease)
we know that force = mass x acceleration,
we have our mass but need to find the acceleration. we can get the acceleration by applying the formula below

therefore
0 = 10.5^{2} + (-2)× a × 0.0735[/tex]
a =
}[/tex]
a = 750
from F = m x a
force = 7.25 x 750 = 5437.5 N
When speed slows down you have kinetic energy.
Answer:
it wont be because the hand brake would be on
Assuming the object is on earth the objects weight would be equal to its mass multiplied by the gravitational field constant
mass=22kg
g=9.80665N/kg
weight=(22 kg) (9.80665 N/kg)=215.7463N
generally g is rounded to be 10 N/kg so for any question where it asks the weight given the mass just multiply by 10 and that should suffice. In this case the answer would be 220 N
