Answer 1

Answer:

The kinetic energy of ball is 9.75 J.

Explanation:

Given that,

• Mass of ball (m) = 780 g
• Velocity of ball (v) = 5 m/s

We know,

↪1 gram = 1000kg

↪Mass of ball (m) = 780/1000 = 0.78kg

So,

${ \boxed{ \blue{ \sf{K.E = \frac{1}{2} \times mv {}^{2} }}}}$

[ Putting values ]

$\leadsto \sf \: K.E \: = \frac{1}{ \red2} \times \red{ 0.78 }\times 5^{2} \\ \\ \leadsto \sf \: K.E \: = 0.39 \times 25 \\ \\ \leadsto \sf \: { \underbrace{K.E \: = 9.75joule}} \: \: \green \bigstar$
