What kinetic energy has a 4kg shootput thrown with a velocity of 12m/s

288J

Step-by-step explanation:

recall the formula for kinetic energy

KE = (1/2) mv²

where m is the mass (= 4kg)  and v is the velocity(=12 m/s)

hence

KE = (1/2) (4)(12)² = 288J

288 Joules

Step-by-step explanation:

K.E = 1/2* mass * square of the velocity

K.E = 1/2 * m * v ^ 2

From the question:

Mass = 4kg

Velocity = 12m/s

Therefore:

K.E = 1/2 * 4 * 12^ 2

= 0.5 * 4 * 144

= 288 Joules

answer: i can’t tell you that

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
