A cross- country skier moves from location A to location B to location C to location D. Each leg of the back and forth motion takes 1 minute to complete; the total time is 3 minutes . Wes =0 min t - 2min t = 3mim t = 1min 100 What is the distance travelled by the skier in the first 3 minutes? What is the net displacement of the skier in the first 3 minutes? - What is the displacement during the second minute? What is the displacement during the third minute?

hello some parts of your question is missing attached below is the missing part

Answer :

a) 360 m

b) 120 m  ( eastward )

c) -120 m ( westward )

d) 80 m  ( eastward )

Explanation:

given data:

Each leg time = 1 minute

Total time = 3 minutes

t=0        t= 2            t = 3             t = 1

xo =0     x2 = 40     x3 = 120       x1 = 160

a) Distance travelled by skier in first 3 minutes

d = | x1 - xo | + | x2 - x1 | + | x3 - x2 |

    = 160 + 120 + 80 = 360 m

b) net displacement in first 3 minutes

s = ( x1 -x0 ) + ( x2 - x1 ) + ( x3 -x2 )

  = 120 m  ( eastward )

c) displacement during the second minute

s1 = x2 - x1  = 40 - 160  = -120 m ( westward )

d) displacement during the third minute

s2 = x3 - x2 = 120 - 40 = 80 m  ( eastward )

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
