Like all experiments, it's important to keep records of the their experiment procedures so future car designers and experimenters can compare and contrast their results from their experiment and improve their experiment accordingly. I'm pretty sure this is it. Stay cool my man.
2.5 joules according to the formula k=1/2MVsquare we would get 2.5 joules as the answer
Answer:
a. wedge
Explanation:
The wedge machine is used to separate, lift or split
objects. It is triangular in shape with a tapered formation thick and blunt on one end, thin on the other end (the edge)
Explanation:
It is known that the relation between work and force is as follows.
w = 
where,
= angle between the applied force and direction of movement of the object which is zero in this case. As, cos (0) = 1.
Therefore, d = 
(i) For w = 36 J, and F = 9 N then value of d will be as follows.
d = 
= 
= 4 m
(ii) For w = 36 J, and F = 12 N then value of d will be as follows.
d = 
= 
= 3 m
(iii) For w = 36 J, and F = 6 N then value of d will be as follows.
d = 
= 
= 6 m
(iv) For w = 36 J, and F = 18 N then value of d will be as follows.
d = 
= 
= 2 m
