What force is required to give an object with mass 50 kg an acceleration of 8 m/s2?

400 N force will be required.

Explanation:

mass of object = m = 50 kg

Acceleration of object = a = 8 m/s^2

Force = F =?

According to newton's second law of motion,

F = ma     (i)

By putting values in equation (i),

F = (50)(8)

F = 400 N

Hence, 400 N force is required to give an object of mass 50 kg an acceleration of 8 m/s^2.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

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.
