Answer:
it is to do with the static electricity produced by using the comb
Answer:
40000 N
Explanation:
Force: This cam be defined as the product of mass and acceleration.
From the question,
The braking force of the lorry will be the same in magnitude as the force at which the lorry is moving.
F = ma..................... Equation 1
Where m = mass of the lorry, a = acceleration/deceleration of the lorry.
Given: m = 5000 kg, a = 8 m/s²
Substitute these values into equation 1
F = 5000(8)
F = 40000 N
Answer:
We know that, the kinetic energy
ke= \frac{1 }{2} m{v}^{2}
and we also know that the acceleration causes the speed's value to be doubled
Hence, v becomes 2v
When 2v is squared, it becomes 4v^2. After substituting this value in the equation above and comparing it,
We can conclude that the Kinetic Energy has increased
by a factor of 4
The answer is c. velocity
