Question

solve the question in attachment !!!!! ​

Answer 1

Answer:

100j

Step-by-step explanation:

K.E = 1/2mv^2

K.E = 1/2(2)(10)(10)

K.E = (10)(10)

K.E = 100 joules

hope it's helpful

Answer 2

Answer:

• The formula for Kinetic Energy is ½mv².

We are given :

• Mass = m = 2 kg
• Speed = v = 10 m/s

• Hence, using the given information

• ⇒ ½(2)(10)²
• ⇒ (10)²

⇒ 100 J

• Hence, the Kinetic energy of the body is 100 J.

More Information :

• Energy is said to be the capacity of doing work.
• Kinetic energy of a body is the energy that it possesses due to its motion.
• Potential energy of a body is the energy that it possesses due to its rest position.
• Formula of Kinetic energy : ½mv²
• Formula of Potential energy : mgh
