According to recent typical test data, a Ford Focus travels 0.210 mi in 19.4 s , starting from rest. The same car, when braking from 58.5 mph on dry pavement, stops in 148 ft . Assume constant acceleration in each part of its motion, but not necessarily the same acceleration when slowing down as when speeding up.

a. Find this car's acceleration while braking and while speeding up.
b. If its acceleration is constant while speeding up, how fast (in mph) will the car be traveling after 0.250 mi of acceleration?
c. How long does it take the car to stop while braking from 60.0 mph?

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
