kinematic equation
v=u+at
v-u=at
v-u = 1x5
the driver will have increased speed by 5 m/s. actual speeds unknown
B. Tornado destruction
It is based on the amount of damage
Answer:
The force between the charges are not affected.
Explanation:
Given;
distance between two equal charges, R = 2m
The force between the charges is given by;

Therefore, the force between the charges are not affected.
Explanation:
It is given that,
Initial speed of the automobile, u = 65 km/hr =
Final speed of the automobile, v = 0
Deceleration of the automobile, 
We need to find the distance covered by the car as it comes to rest. It can be calculated using third equation of motion as :



So, the acceleration of the car is
. Hence, this is the required solution.
