A bicycle rider travels 50.0 km in 2.5 hours. Determine the cyclists average speed.
k0ka [10]
There are several information's already given in the question. Based on those information's the answer can be easily deduced.

Distance traveled by the bicycle rider = 50 km
Time taken to travel the distance = 2.5 hours
So
In 2.5 hours the bicycle rider travels = 50 km
Then
In 1 hour the bicycle rider travels = 50/2.5
                                                     = 20 km
Then the average speed of the cyclist is 20 km per hour.

A person consumes a snack containing 14 food calories (14kcal). what is the power this food produces if it is to be "burned off"
Inessa05 [86]

Answer:

B) 2.7W

Explanation:

Converting Cal to Joule

        1 cal = 4.186J

        14 kcal = 14 x 1000 x 4.186

                     = 58604 J

Converting hour to seconds

             6 hours = 6 x 60 x 60 seconds

                           = 21600 seconds

Power is the time rate of doing work.

Power = Work/Time

P = (58604) / (21600)

P = 2.7W

How much force is needed to accelerate a 68 kilogram skier at a rate of 1.2m/sec
xxMikexx [17]

Let's use Newton's 2nd law of motion:

                                     Force = (mass) x (acceleration)

                                     Force = (68 kg) x (1.2 m/s²) =  81.6 newtons .
