In the amusement park ride known as magic mountain superman, powerful magnets accelerate a car and its riders from rest to 43.4 m/s in a time of 8.59 s. the mass of the car and riders is 3.00 × 10^3 kg. find the average net force exerted on the car and riders by the magnets.

Average net force, F = 15157.15 N

Explanation:

It is given that,

The mass of the car and riders is,

Initial speed of the car, u = 0

Final speed of the car, v = 43.4 m/s

Time, t = 8.59 seconds

We need to find the  average net force exerted on the car and riders by the magnets. It can be calculated using second law of motion as :

F = m a

F = 15157.15 N

So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the answer would be a
