A squirrel is trying to locate some nuts he buried for the winter. He moves 4.3 m to the right of a stone and dogs unsuccessfull
krek1111 [17]

Answer:

The total displacement from the starting point is 1.5 m.

Explanation:

You need to sum and substract, depending on the movement (to the right, sum; to the left, substract).

First, it moves 4.3 m right and return 1.1 m. So the new distance from the starting point is 3.2 m.

Second, it moves 6.3 m right, so the new distance is 9.5 m.

Finally it moves 8 m to the left, so 9.5 m - 8 m= 1.5 m.

Summarizing, at the end the squirrel is 1.5 m from its starting point.

MArishka [77]

Answer:

Explanation:

given ;

  • coefficient of kinetic friction = 0.80
  • mass m = 26kg
  • considering the force acting in horizontal direction and from newton's 2nd law of motion;
  • for vertical motion = Fn - mg = 0
  • for horizontal motion = F = ma + miu mg = m( a + miu.g)
  • but a = 0
  • therefore, F = miu mg where g = 9.81m/s^2
  • plugging the values into the equation;
  • F = 0.80 x 9.81 x 26

Horizontal force = 204.05N

A water skier has a mass of 79.0 kg and accelerates at 1.40 m/s2. What is the net force acting on him? F = ___ N
marysya [2.9K]
The answer is 111.

Using Newton's Second Law, F=ma, plugging known values in we get:

F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N
