At the Billings Auto and Highway Safety Testing Lab, a car with a crash-test dummy inside travels at 38.89 m/s (87 mi/h) toward a stationary car during a crash test. The
moving car takes 0.65 s from the point of car impact to the time when the car comes to a
complete stop. Calculate the deceleration of the car.

1) a child holds two dogs on two separate leads. the dogs are pulling in different directions. one is pulling a force of 20n north and one is pulling 15n eastwards. calculate the resultant force on the child. state the direction. (use the parallelogram of forces) 2) a force of 20n acts horizontally on an object. a second force of 5n acts at 60 degrees to the first one. calculate the resultant force. worth 20 points, need answers asap with method you x
