Answer:
a = 16 m/s²
Explanation:
The mass of the object, m = 200 kg
The radius of the circular motion, r = 4 m
The speed of the object, v = 18 m/s
The centripetal acceleration is given by the relation,
a = v²/r
Substituting the given values,
a = 18 / 4
= 16 m/s²
Hence, the centripetal acceleration of the object is, a = 16 m/s²

Explanation:
In order to convert the heat from calories to joule, we must remember the conversion factor:
1 cal = 4.184 J
Keeping in mind this, we can set up a proportion to find how much Joules correspond to 12,400 calories:
