If the mass of a ball is 20g and h is 8m, calculate the kinetic energy when it has a velocity of 2ms raise to power minus 1

Thanks guys

Ke -1/2mv^=(1/2)(0.02)(2)=0.02j.

To calculate the kinetic energy of a ball, you can use the formula:

Kinetic Energy = (1/2) × mass × velocity^2

Given:
mass = 20g (or 0.02kg)
velocity = 2m/s^(-1)

Step 1: Convert the mass from grams to kilograms.
mass = 20g = 0.02kg (since 1 kilogram = 1000 grams).

Step 2: Substitute the values into the kinetic energy formula.
Kinetic Energy = (1/2) × 0.02kg × (2m/s^(-1))^2

Step 3: Simplify the expression.
Kinetic Energy = (1/2) × 0.02kg × 4m^2/s^(-2)

Step 4: Calculate the result.
Kinetic Energy = 0.04 joules (J)

Therefore, the kinetic energy of the ball when it has a velocity of 2m/s^(-1) is 0.04 joules.

h doesn't matter

KE = 1/2 mv^2 = (1/2)(0.02)(2) = 0.02J

all those words are just noise.
v is 2 m/s, much easier to read.
