Explanation:
it's generally proven that the formula for kinetic energy is k. e = ½mv²
= ½×2×3
=3
Answer:
Explanation:
The problem is based on conservation of angular momentum.
Moment of inertia of the disc = 1/2 m R² , m is mass of the disc and R is its radius.
= 1/2 x 98.1 x 1.51²
= 111.84 kg m²
Moment of inertia of disc + moment of inertia of bananas + monkey
= 1/2 x 98.1 x 1.51² + 9.29 x .45 x 1.51 + 20.3 x 1.51² ( moment of inertia of banana and monkey will be equal to mass x radial distance from axis² )
= 111.84 + 6.31 +46.28
= 164.43 kg m²
Now applying law of conservation of angular momentum
= I₁ ω₁ = I₂ω₂
111.84 x 1.69 = 164.43 x ω₂
ω₂ = 1.15 rad / s
Answer:
Deceleration is the opposite of acceleration.
The mathematical formula for deceleration is:
Uniform deceleration of an object can be defined as decreasing the velocity of an object in equal amount in an equal interval of time.
The graph attached below shows a constant decrease in the velocity with a uniform time interval.
