An 18-wheeler with a mass of 35,000 kg is moving at a speed of 65 mph or about 30 m/s. If this vehicle collides with a barrier and the collision lasts one tenth of a second (0.1 s), what is the force experienced by this vehicle?

Answer 1

The force experienced by the 18-wheeler can be calculated using the equation F = Δp/Δt, where Δp is the change in momentum and Δt is the duration of the collision. By calculating the change in momentum, which is equal to the mass of the vehicle multiplied by its final velocity (since the initial velocity is assumed to be zero), and dividing it by the duration of the collision, we can find the force experienced by the vehicle.
