Answer:
200 N
Explanation:
The crowbar is 2 meter, or 200 cm. The effort arm is 160 cm, so the moment arm of the object is 40 cm.
(800 N) (40 cm) = F (160 cm)
F = 200 N
I think it’s the first option
Answer:
The acceleration of car 2 is four times of the acceleration of car 1.
Explanation:
The centripetal acceleration of the object is possessed when it moves in a circular path. It is given by :

In this case, two race cars are driving at constant speeds around a circular track. Both cars are the same distance away from the center of the track, but car 2 is driving twice as fast as car 1.
So,

1 and 2 represent car 1 and car 2 respectively.

So,

So, the acceleration of car 2 is four times of the acceleration of car 1.
