Newton stated 3 laws that rules moving bodies:
First law - an object remains in its state (resting or moving at constant speed) unless acted upon a force
Second law - the force (F) of an object is equal to its mass (m) multiplied by its acceleration (a); F = m x a
Third law - when an object exerts a force upon another, the second object exerts a force that is equal in magnitude and opposite in direction
So, according to the First Law of Motion, the metor moving through outer space will continues its motion until an outside force acts upon it
Answer:
W = 343.2 J
Explanation:
Given that,
Mass of bale of hay = 26 kg
Horizontal force exerted = 88 N
Distance moved, d = 3.9 m
Work done, W = Fd
Put all the values,
W = 88 N × 3.9 m
= 343.2 J
So, the work done is 343.2 J.
Explanation:
Given that,
An object in free fall will fall d feet in t seconds, where d and t are related by the algebraic model as :
..........(1)
(a) We need to find the time taken by the object to fall 1148 ft. Put this in equation (1) as :
t = 8.47 seconds
(b) If the object is in free fall for 18.5 sec after it is dropped, then the height of the object is given by :
d = 5476 ft
Hence, this is the required solution.
