Question

What will be the kinetic energy of an object of mass 100 grams after 3 secoends of uninterrupted reading from a height of 500 meters?

Answer 1

Answer:

Explanation:In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

Answer 2

Answer:

mass(m)=100g=0.1kg

height (h or x) =500m

time(t)= 3 sec

Velocity(v)= x/t=500/3= 166.67m/s

Kintic energy(E.K.)=(1/2) mv^2

E.K.= 1/2×0.1×[500/3]^2

E.K=1388.92J

Explanation:

Required kinetic energy=1388.92J
