Question

A bobsled moving at 32 m/s decelerates to 22 m/s at a rate of 4.8 m/s2. determine the distance traveled by the bobsled during this time

PLEASE SHOW YOUR WORK

Answer 1

The vehicle travels 56.25 metres in the interval during which body decelerates .

Step-by-step explanation:

• Initial velocity of vehicle, u = 32 m/s

• Final velocity of vehicle, v = 22 m/s

• Rate of acceleration, a = - 4.8 m/
  `s^(2)`

Let the distance travelled be s .

We have to determine the distance travelled by the vehicle during this time.

The equation of motion is given by

`v^(2) - u^(2) = 2 * a * s`

`(22)^(2) - (32)^(2) = 2 * (- 4.8) * (s)`

`1024 - 484 =9.6 * (s)`

s =
`(540)/(9.6)`

s = 56.25 metres

The vehicle travels 56.25 metres in the interval during which body decelerates .
