Question

Определите кинитическую энергию автомобиля массой 1,5 т, движущегося со скоростью 20м/c

Answer 1

Ek=mu^2/2
Ek=1500*400/2=300000 Дж

Answer 2

Calculation of Kinetic Energy

To calculate the kinetic energy of an object, we can use the formula:

Kinetic Energy (KE) = (1/2) * mass * velocity^2

Given that the mass of the car is 1.5 tons (or 1500 kg) and the velocity is 20 m/s, we can substitute these values into the formula to find the kinetic energy.

KE = (1/2) * 1500 kg * (20 m/s)^2

Let's calculate the kinetic energy:

KE = (1/2) * 1500 kg * 400 m^2/s^2

KE = 300,000 Joules

Therefore, the kinetic energy of the car with a mass of 1.5 tons and a velocity of 20 m/s is 300,000 Joules.
