A car weighing 1500 kg drives at 5m /s when it collides with a wall. It takes 0.20 seconds until the car is completely stationary. The driver weighs 90 kg. How much average force is the driver under the crash?

2250 N

Explanation:

Assuming the driver decelerates at the same rate as the car:

a = (0 m/s − 5 m/s) / (0.20 s)

a = -25 m/s²

F = ma

F = (90 kg) (-25 m/s²)

F = -2250 N

The magnitude of the average force on the driver is 2250 N.

spare some change and give it to the poor

explanation:

plz : ((

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
