A cross-country skier is skiing along at a zippy 8.0 mis. She stops pushing and simply glides along, slowing to a reduced speed of 6.0 mis after gliding for 5.0 m. What is the magnitude of her acceleration as she slows

Explanation:

We are given that

Initial speed,u=8 m/s

Final speed,v=6 m/s

Distance,s=5 m

We have to find the magnitude of her acceleration as she shows.

We know that

Using the formula

Magnitude of acceleration=

Acceleration, a =

Explanation:

Given that,

Initial speed of the skier, u = 8 m/s

Final speed of the skier, v = 6 m/s

Distance, d = 5 m

We need to find the magnitude of her acceleration. It is equal to the rate of change of speed. It is given by :

So, the magnitude of her acceleration is .
