Answer:
The correct answer is t = 0.92s
Explanation:
Initial velocity v0 = 3.0 m/s
Displacement Δy = ?
Acceleration a = -9.8m/s2
Final velocity v = -6.0m/s
Time t=? Target unknown
We can use the kinematic formula missing Δy to solve for the target unknown t:
V=v0+at
We can rearrange the equation to solve to t:
V-v0=at
t= v-v0/a
Substituting the known value into the kinematic formula gives:
t= (-6.0m/s)-(3.0m/s)
————————————
-9.8m/s2
= -9m/s
—————-
-9.8m/s2
=0.92s
Answer:d
Explanation:
Probably becuase it is further than Saturn
It takes like 70 years to go around the sun
And it is bigger than the moon
Answer with explanation:
We know that when we weigh ourselves on a scale the scale measures the Reaction force that acts between the scale and the person who wishes to determine his weight.
The free body diagram of the person on a weighing scale is represented in the attached figure.
As we can see for equilibrium
where,
R is the reaction force between the support and the person
W is the weight of the person which by definition is the force that the earth exerts on the person.
Thus according to the above relation we conclude that that support force of the scale is equal to the gravitational force in magnitude but is opposite in direction.
