an object with a mass of 5kg is moving with an initial velocity of 20m/s.the object accelerates at a rate of 15m/s/s for 8s.what
is the net force on the ball during acceleration?
1 answer:
It doesn't matter what the object's initial velocity is, or how long
the acceleration lasts. All that matters is the object's mass and
acceleration.
Force = (mass) x (acceleration) =
(5kg) x (15 m/s²) =
75 kg-m/s² = <em>75 newtons .</em>

Answer:
Moment of inertia of Earth about its own axis is given as
Explanation:
Since Earth is considered as solid sphere
So we will have
so we will have
so we have
Resitance (R)= 10 Ohm
Potential difference (V) = 9V
V= IR
I= V/R
I= 9/10
I= 0.9 Ampere
Therefore 0.9 Ampere of current is flowing through the circuit.
