A motorcycle is waiting at a stoplight. When it finally turns green, the motorcycle accelerated
from rest at a rate of a 7.45 m/s 2 for a time of 3.90 seconds. Determine the displacement of the
motorcycle during this time period.

56.65 m

Explanation:

Using second equation of motion

S = vit + 1/2 at^2

s = 0x3.9 +0.5x7.45x (3.9)^2

= 56.65 m

it should be -8.6 cm hope this out

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
