Answer:
16.87 m/s
Explanation:
To find the speed of the car at the top, when the normal force is equal the gravitational force, we just need to equate both forces:
is the centripetal acceleration in the loop:
So we have that:
So, using the gravity = 9.81 m/s^2 and the radius = 29 meters, we have:
The speed of the car is 16.87 m/s at the top.
Homo Habilis was a secies of the tribe Hominini, which lived between 2.4 and 1.5 million years ago. His name means "handy man" or "able man". Homo habilis was short, with disproportionately long arms compared to modern humans. His remains are often acompanied by primitive stone tools.

A class action law suit is one in which the courts allow several
people who all claim to have been harmed to pool grievances
and sue for damages on behalf of the group.
The objects have different densities
They objects may possess the same volume; however, due to a difference in density, they do not possess the same mass within that volume. This means that they experience a different gravitational force, which causes one to sink and the other to float.
