Earth's moon has been identified as a "regular" moon by your textbook authors, but many planetary scientists (including your instructor) disagree with this classification. why does earth not fit the typical criteria of regular moons? check all that apply. (a)the moon is tidally-locked to earth. (b)the moon is very large compared to earth. (c)the moon does not orbit in earth's equatorial plane. (d)the moon has maria unlike other regular moons. (e) the moon did not form from the same cloud of material as earth. (f)the moon has a significantly different composition from earth. (g) the moon formed in a giant impact.

magnitude and direction

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
