Answer:
45
Explanation:
because the equation for speed is distance divided by time! hope that helps gave a nice day!
Wooden desk it doesn’t conduct or absorb heat as much as metal or plastic
Answer:
218.5 N
Explanation:
In order for the sled to be in equilibrium along the vertical direction, the forces acting along this direction must be balanced. So the equilibrium equation is:
where
N is the normal force
F = 50 N is the force that pulls the sled
is the angle between the force and the horizontal, so
is the component of F acting along the vertical direction
(mg) is the weight of the sled, with
m = 25 kg being the mass of the sled
g = 9.8 m/s^2 is the acceleration due to gravity
Solving the formula for N, we find
'Gram', 'kilogram', and 'metric ton' are units of mass, not weight.
'Pound' can be either a unit of mass or of force. Most people
use it most of the time to mean weight.
<span>I found out F2 and its correct just need help in solving the other parts </span>
<span>F2 = 4.5 N </span>
