Two identical trucks traveling at different constant speeds are about to collide. The trucks are traveling in opposite directions with truck A going at a velocity of 3m/s right and truck B going at 4m/s left.
During the collision, will the magnitude of the acceleration of truck A be (a) greater than, (b) equal to, or (c) less than the magnitude of the acceleration of truck B?
The Attempt at a Solution
I thought the answer would be (b) equal to, since they both travel at a constant velocity, but then I realised that during the collision they would be decelerating and so I think that it would be (c) less than, since truck A is going at a slower velocity than truck B and so it would decelerate less.
Can anyone tell me if I'm right or wrong and explain why? thanks
