Constants I Periodic Table Brain injuries in auto accidents. Brain injuries generally occur any time the brain's acceleration reaches 100 g for even a short time. Consider a car running into a solid barrier. With an airbag, the driver's head moves through a distance of 20 cm while the airbag stops it. Without an head continues forward until the seatbelt stops the torso, causing the head to stop in a distance of only 5.0 cm. Part A Find the maximum speed with which the car can strike the barrier without causing brain injury, using an airbag airbag, the Express your answer to two significant figures and include the appropriate units. ?

Example An experimental device imparts a force of magni- tude F = 225 N to the front edge of the rim at A to simulate the effect of a slam dunk. Determine the 900 mm 700 mm F moments of the force F about point O and about point B. Finally, locate, from the base at 0, a point C on the ground where the force imparts zero moment.

Hi I am looking for help with problem #4

Constants Periodic Table Carla holds a ball 1.5 m above the ground. Daniel, leaning out of a car window, also holds a ball 1.5 m above the ground. Daniel drives past Carla at 40 mph and, just as he passes her, both release their balls at the same instant. Part A Whose ball hits the ground first? O The balls will hit the ground simultaneously. Daniel's. Carla's. The answer can't be determined from the data provided.

In an experiment, a bump car is allowed to travel freely from one end to another in a meter stick. When it hits one end, the car bounces back 6 meters and then move forward again. On each bounce, it moves back 2/3 of the distance is it previously , traveled. a.) determine the distance covered by the bump car from the head wall after 4 bounces. b.) solve for the total distance traveled by the car after 5 bounces.

Part A Drop Tower NASA operates a 2.2-second drop tower at the Glenn Research Center in Cleveland, Ohio. At this facility, experimental packages are dropped from the top of the tower, on the 8th floor of the building. During their 2.2 seconds of free fall, experiments experience a microgravity environment similar to that of a spacecraft in orbit. What is the drop distance of a 2.2-s tower? Express your answer using two significant figures. ΑΣΦ ? Submit Request Answer • Part B How fast are the experiments traveling when they hit the air bags at the bottom of the tower?
