Question
A small car makes a head-on collision with a large truck on an icy pavement. Before they collide, they were traveling with the same speed (but in opposite directions). (a) During the collision, which vehicle experiences the greater collision force? (b) During the collision, which vehicle experiences the greater acceleration? (c) Which vehicle had the larger change in momentum? (d) Which vehicle had the larger change in velocity? (e) Assuming the car driver and the truck driver have the same mass, which driver experiences the greater force during the collision?Explanation / Answer
a) Both the truck and car will experience equal Force in opposite directions .This is according to Newtons Third Law
b) Here, as Both experience equal Force , but mass of car is less than mass of truck . So, Car will experience greater acceleration than truck .
c) As, momentum is conserved during collision .So, Both of the vehicle has same change in momentum .
d) As, Both of the vehicle has same change in momentum and mass of car is less than mass of truck . So, Car has a larger change in velocity .
e) Here, Force experienced by Car driver is more than Force experienced by truck driver . Because , Car experience greater acceleration than truck .
