Aball that has a mass of 0.25 kg spins in a circle at the end of a 1.6 m rope. the ball moves at a tangential speed of 12.2 m/s. what is the centripetal force acting on the ball? a 1.9 n b 23 n c 59 n d 93 n

(B). The centripetal force acting on the ball is 23 N.

Explanation:

Given that,

Mass m = 0.25 kg

radius r = 1.6 m

Tangential speed = 12.2 m/s

The centripetal force formula as:

Where, m = mass

v = tangential speed

r = radius

Put the value of m,v and r in equation (I)

Hence, The centripetal force acting on the ball is 23 N.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

i think the answer would be reserve.
