When a person is involved in a car accident, why is the likelihood of injury greater in a head-on collision as opposed to being hit from behind? answer using the concepts of relative velocity, momentum, and average force. (select all that apply.)1.the change in momentum is greater in the head-on collision.2.the momentum of the driver relative to the ground is greater in a head-on collision.3.the velocity of the driver relative to the ground is greater in a head-on collision. 4.the average force on the driver is greater in the head-on collision.5. the collapse of the crumple zone in the front of the car occurs only in the head-on collision.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
