What expression (formula) relates Kenetic energy of an object of mass to its momentum
1 answer:
Answer:
Correct answer: Ek = I² / 2 · m
Explanation:
The formula by which kinetic energy is calculated is:
Ek = m V² / 2
The formula by which momentum i prefer the name impulse is calculated is:
I = m V
We will transform the formula for kinetic energy on the next way:
Ek = m V² / 2 we will multiply numerator and denominator with m and get:
Ek = m² V² / 2 m = (m v)² / 2 m = I² / 2 m
Ek = I² / 2 m

Answer:
<h2>5.3N</h2>
Explanation:
Step one:
given data
mass of bullfrog= 0.54kg
Step two:
Required
The force F in Newton
From newton first law
F=mg
The acceleration due to gravity acting on the frog is 9.81m/s^2
hence
F=0.54*9.81
F=5.3N
The normal force is 5.3N
