The creators of Spiderman 2 are blissfully unaware that there really isn't any difference between the rapid acceleration caused by sudden impact with a truck and the equally rapid acceleration caused by sudden impact with spiderman. I love it when he comes swooping down out of the sky to brush people out of the way of wayward vehicles.

In slow-mo I calculated that he brought the two kids from a standstill to the side of the road (let's say... ~5 meters) in about 3 frames, or at 24fps, that's 5 meters in 0.125 seconds. Now lets be generous and assume that the acceleration due to Spiderman is constant (this would be the least-damaging scenario to our defenseless children) rather than what it looks like, which is delta-function instantaneous acceleration which would turn them into hamburger. In this case, the acceleration on the children would have to be 2*5/(0.125²) = 640 m/s². This, of course, is roughly 64 times the force of gravity. 64 g's. Spiderman, you lousy rat, you killed the kids. If he would have just stuck to delivering his pizzas, maybe he wouldn't have gotten fired. The kids would have died anyway.
