Answer:
d = 4.9 m
Explanation:
It is mentioned that a stone is dropped from a certain height. It is required to find the distance covered by it in one second.
The initial speed of the stone is equal to 0 as it was at rest. Let d is the distance covered by the stone.
Using second equation of motion :
Put u = 0 and a = g
So, the distance covered by it in one second is 4.9 m.

Answer:
true
Explanation:
for example assume you are setting in a moving bus and when someone see you from the ground you are in motion but for some who is with you in the bus you are not in motion.
Answer:
Explanation:
Let the mass of the other car is "m" and its kinetic energy is
now the mass of the first car is two and half times and its kinetic energy is half that of other car
so we will have
now speed of both cars is increased by value of 9 m/s
so now we will have same kinetic energy for both cars
so speed of first car is
