Answer:
(a) 34.48N
(b) 27.7664N
(c)41.209N
Explanation:
Following relation gives force of kinetic friction.
, u is coefficient of of kinetic friction , is force normal or perpendicular to surface which is given by , a is acceleration normal to surface.
In case of b and c, a is varied because of the acceleration of elevator and in case a it remains because elevator is stationary and acceleration is only due to earth's gravity.
so in case b and in case c (it is net acceleration ).
substituting all this in original relation gives.
(a)
(b).
(c) .
Answer:
Although the Earth has a lesser mass than the Sun, it is far closer to you, allowing for a stronger pull.
