Question

What is the Kinetic Energy of a ball moving with a velocity of 2.75m/s and a mass of 2kg? Use the formula KE = 1/2 mv squared

Answer 1

Step by Step solutions for finding kinetic energy

Given:

M= 2kg

V= 2.75m/s

Unknown:

KE or kinetic energy of the ball moving

Formula:

KE= 1/2 m v²

Solution:

KE= 1/2(2kg)(2.75 m/s)²

KE= (4kg)(7.56 m²/s²)

Final Answer:

KE= 30.25 kg.m²/s² simplify as 30.25 J
