a car that travels at a speed of 20m/s and has a mass of 12ookg
momentum = m v = 20*1200 = 24,000 kg m/s
Ke = (1/2) m v^2 = 600*400 = 240,000 Joules
To find the momentum of the car, we can use the formula: momentum (p) = mass (m) × velocity (v). In this case, the mass of the car is given as 1200 kg, and the speed is given as 20 m/s.
To calculate the momentum, simply multiply the mass and velocity together.
Momentum (p) = Mass (m) × Velocity (v)
p = 1200 kg × 20 m/s
p = 24000 kg·m/s
Therefore, the momentum of the car is 24000 kg·m/s.
