Here object is dropped from height "h"
so we can say its initial speed is zero
and it will accelerate downwards due to gravity
now we can say it will take time T to hit the ground
now we can use
now it is given that it will take 1 second to drop h/2 height to strike the ground
so here we have can say that in "T - 1" s it will cover the h/2 distance from start
now we can say
from above two equations we have
now we can find total height of the drop by first equation
Answer: A
Explanation: the tilted axis’s allows the sun to hit areas with different amount of radiation therefore leading to seasons
Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
Answer: Vector quantity is a measurement that has both magnitude and direction.
Explanation:
Vector quantity is a measurement that has both magnitude and direction. Examples are force, acceleration, displacement and velocity.
V=s/t. All you need to do is
s=v×t=330×1.8
