The ball has a mass of 2 kg and the velocity of 8 m/s. What
is the KINETIC ENERGY of the ball?
A. 63 B. 163 C. 64N
D. 643​

Answer:

the answer is 64

Step-by-step explanation:

G: m=2kg v=8m/s

R: KE?

S: KE mv²

KE: 2kg × (8m/s)²

KE: 2kg × 64 m²/s²

KE: 128 kg m²/s² ÷ 2

KE= 64J

Answer:

64J

Step-by-step explanation:

Formula:

[tex] \\ \sf{}K.E. = \frac{1}{2} {mv}^{2} [/tex]

K.E. = Kinetic Energy = ?

M = mass = 2kg

V = velocity = 8m/s²

[tex]\\ \sf{}K.E. = \frac{1}{2} (2kg)(m/s ) {}^{2} [/tex]

[tex]\\ \sf{}K.E. = \frac{1}{2} (2kg)(64m/s^{2})[/tex]

[tex]\\ \sf{}K.E. = \frac{1}{2} \bigg(128kg.m/s^{2} \bigg )[/tex]

[tex]\\ \sf{}K.E. = \frac{128kg.m/s^{2}}{2} [/tex]

[tex]\\ \huge \boxed{\sf{}K.E. =64J} \\ \\ \\ [/tex]
