Let the first car's average speed be x
The second car's speed would be x+5
So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
The second car's speed would be x+5
So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
Answer:
<em>The mass of the object is 40 Kg</em>
Explanation:
<u>Net Force</u>
According to the second Newton's law, the net force exerted by an external agent on an object is:
F = m.a
Where:
a = acceleration of the object.
m = mass of the object.
The mass can be calculated by solving for m:
The object has a net force of F=600 N acting on it and travels at , thus the mas is:
m = 40 Kg
The mass of the object is 40 Kg
