A DRIVER TRY TO STOP WHEN SEES A DEER. tHE FASTES HE CAN DECCELERATE IS 4.3M/S2. hOW LONG WILL IT TAKE TO STOP

Question

THE DRIVER WAS DRIVING 12.2M/S WHEN HE TRY TO STOP

Answer 1

Not long enough for the deer.

Answer 2

If he is driving a MAC truck there is no need to worry.  But 12.2 meters per second is increadibly slow for a deer, about 27.45 MPH.  I doubt the deer would have any problem avoiding the truck.

Answer 3

12.2/4.3 = 2.837 seconds

Answer 4

Sorry don't know what 4.3M/S2 is...     When I went to school it was feet and inches....

Answer 5

Depends on the size of the deer.

If the deer is big enough, the car will stop almost instantly (causing certain death to the vehicle occupants).

Answer 6

Use v = u + at, where v is the final velocity, zreo in this case, u the initial velocity, 12.2 m/sec, a is -4.3 m/sec/sec (negative because he`s slowing down), and t the time it takes for him to stop, so:

v = u + at,

0 = 12.2 - 4.3t, so

4.3t =12.2, so

t = 12.2/4.3, so

t = 2.84 seconds.

Answer 7

at least 2.8 seconds
