The investigator imagines several likely scenarios that may have led to to the accident. Maybe the driver was intoxicated, fell asleep or was speeding; maybe mechanical failure or bad weather conditions.
The investigator might order a blood alcohol level test; check the car parts, test drive the car in different weather conditions to replicate the skid marks left by the car.
A car travels from city K to city Q (100. km). If the first half of the distance is driven at 50. km/h and the second half is driven at 100. km/h, what is the average speed for the trip?
A car travels from city K to city Q (100. km). If the first half of the time was at 50. km/h and the second half is spent at 100. Km/h, what is the average speed for the trip?
A bicyclist accelerates from 5.0 m/s to a velocity of 16 m/s in 8 s. Assuming uniform acceleration, what distance does the bicyclist travel during this time interval?
An aircraft has a landing speed of 302 km/h. The landing area of an aircraft carrier is 195 m long. What is the minimum uniform acceleration required for a safe landing?
What is the acceleration of the orange at its lowest position? What is the orange’s acceleration at its highest position? How high would the orange go, if there was no air resistance?
In movies people often jump from buildings into pools. If a person jumps from the 10th floor (30.0 m) to a pool that is 5.0 m away from the building, with what initial velocity must a person jump?
A flying, stationary kite is acted on by a force of 9.8 N downward. The wind exerts a force of 45 N at an angle of 50.0 o above the horizontal. Find the angle and the force that the string exerts on the kite?
