Acceleration and deceleration and momentom
they slow the car down and it loses momentome
Speed = Distance/Time = 100 km / 4 hours = 100/4 km per hour = 25 kph
Answer:
6.48 m/s
Explanation:
We are given that
Mass,M=2 kg
Radius,R=0.25 m
Height,h=3 m
Moment of inertia of solid sphere=
We have to find the linear speed.
By law of conservation of energy
Where
Substitute the values
Given two charges,
and
, we can calculate for the electric force with
with k as the Coloumb constant and r as the distance given to be 3 cm or 0.03 m. Plugging this in, we have
Thus, we have F = 10 N.
Answer: 10N
