Answer:
61 degrees, I just did the test.
Explanation:
First of all, the question is worded somewhat ambiguously because mass does not necessarily imply that there is a force (i.e. an object could be stationary in a system with no gravity and not have a force, or something of the like). Moreover, simply because an object is twice the mass does not mean the force will change.
However, we know from Newton's second law that F = ma. Therefore, force will increase or decrease proportionally with mass. This means if an object maintains a contestant acceleration and its mass doubles, the force that it provides will also double.
By the Newtons Second Law:
F = ma
F = (47 kg)(15 m/s²)
<h2>F = 705 N</h2>
Answer:
Explanation:
We shall apply law of conservation of momentum to know the Speed of northward moving vehicle before collision to check the veracity of driver's statement .
Let v be the velocity of composite mass after collision
Applying law of conservation of momentum in north direction
m v₂ = 2m v sin55.08
Applying law of conservation of momentum in east direction
m x 13 = 2m v cos55.08
Dividing these two equations
v₂ / 13 = tan55.08
v₂ = 13 tan55.08
= 18.62 m/s
= (18.62 x60 x 60) / 1000
= 67 km/h
= 67 x 5/8 mi/h
= 42 mi/h
So he is lieing.
Atoms are made up or one or more molecules
