Answer:
-10 N, not balanced
Explanation:
Force is a vector quantity, so in order to find the net force on an object, we must use vector addition rule.
This means that if two forces acting on an object along the same line, we have to choose one direction as positive, and write the two forces with the correct sign.
In this problem, we have two forces acting along a line on the car:
- A first force of
- A second force of
Therefore, the net force on the car is:
Moreover, the net force on an object is said to be "balanced" if it is zero: in this case, it is not zero, so it is not balanced.
Answer:
the sum of all forces acting on an object.
Explanation:
Answer:
5.3×10⁴ m/s
Explanation:
From the question,
Momentum = mass× velocity
M = mV................ Equation 1
Where M = momentum of the airplane, m = mass of the airplane, V = Velocity of the airplane
make V the subject of the equation
V = M/m.................. Equation 2
Given: M = 1.6×10⁹ Kg.m/s, m = 3.0×10⁴ kg
Substitute these values into equation 2
V = 1.6×10⁹/3.0×10⁴
V = 5.3×10⁴ m/s
