Answer:
The average death rate for this type of event is closest to 350 people per event.
Explanation:
Between the years 2048 and 2057
Is 10 years. Since there is only one chance of event between these years, there is no point to consider it.
The total number of events = 2940 chances.
average death rate per event = total number of dead people divided by total number of events of occurrence.
1000000/2940 = 340.134
The average death rate for this type of event is therefore closest to 350 people per event
Answer:
39.240 W
Explanation:
Let's start by calculating the work done by the engine. We can assume that it is the same work done by the weight of the object to bring it from 40m to the surface: as much energy it takes to bring it up, the same ammount it takes to bring it down. Said work is 
At this point we can simply apply the definition of power, that is 
, to get the power of the engine is 
Work Done = Force x Distance Moved
Work Done = 25 x 15 = 375 Joules
Answer with Explanation:
Newton's laws are applicable for inertial frames of reference which is a frame which is not accelerating when seen from the observer standing on earth.
For the person as he presses the brakes his frame is a decelerating frame of reference hence he cannot apply the newtons laws of motion as they are in their original form but if he analyses the motion he has to apply a correction known as pseudo-force on the object he is analyzing. Pseudo Force has no basis in newton's laws but are a correction that needs to be applied if he wishes to analyse the motion from non inertial frame of reference
While as a person standing on earth outside the car since his frame is an inertial frame of reference he can apply newton's laws of motion without any correction.
