Answer:
A car would need to be moving with a velocity of 28.86 m/s for its acceleration to be numerically equal to the acceleration due to gravity.
Explanation:
Radial acceleration for an object in circular motion is given by
α = v²/r
α = g = 9.8 m/s²
v = ?
r = 85 m
9.8 = v²/85
v² = 9.8 × 85 = 833
v = 28.86 m/s
Answer:
C. Angular Separation
Explanation:
The term angular distance (or separation) is technically synonymous with angle itself, but is meant to suggest the (often vast, unknown, or irrelevant) linear distance between these objects (for instance, stars as observed from Earth).
V= s/t
=
5.15/ 350
=68.0 km/h
