Answer:
20000 kg*m/s
Explanation:
Momentum is equal to mass * velocity. So plug in 1000 kg and 20 m/s for mass and velocity respectively to get 1000*20 = 20000. Be sure you convert to the correct unit when doing future problems
An increase in average speed of 1 km/h typi- cally results in a 3% higher risk of a crash involving injury, with a 4–5% increase for crashes that result in fatalities. — Speed also contributes to the severity of the impact when a collision does occur. Hope this helps!
In mechanics, the normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact, of the contact </span>force<span> exerted on an object . We calculate as follows:
