Una pelota recorre 20 m hacia la derecha y luego 10 m hacia la izquierda, todo en un lapso de tiempo de 10 s , cual es si veloci
zvonat [6]

Answer:

v = 1  i ^ m / s,   v = 1 m / s

Explanation:

In this problem we show the difference between vectors and scalars.

The average speed is

          v = Δx / Δt

The bold are vectors            

          Δx = 20-10 = 10 i^  m

           v = 10/10

           v = 1  i ^ m / s

the unit vector indicates that the velocity is on the x-axis

The average speed is

           v =Δx / Δt

           v = 10/10

           v = 1 m / s

in this case we have a scalar

A pitcher releases a fastball that moves toward home plate.
Vsevolod [243]

The two additional forces that act on the ball as it travels between the pitcher and the home plate are air resistance and gravity.

<h3>What are the forces that affect object in motion;</h3>
  • Air resistance: this is the force that oppose the motion of an object in air due to frictional force
  • Gravity: this is the force due to weight of the object and acts downwards.

The two additional forces that act on the ball as it travels between the pitcher and the home plate include:

  1. Air resistance and
  2. Gravitational force  

<h3>How the forces affect the motion of the ball</h3>
  • Air resistance oppose the motion of the ball as it travels in air.
  • Gravity is the force due to weight of the ball and acts downwards.

How far can a mother push a 20.0 kg baby carriage, using a force of 62 N, if she can only do 2920 J of work? (Round to include t
alexgriva [62]
The mathematical definition of work (W) is force (F) multiplied by distance (x). In order to determine the distance for fixed force and work the above equation needs to be rearranged to make x the subject. The work divided by the force is equal to the distance. In this case the mother can push the baby carriage by a distance equal to 2920 divided by 62, which is 47.1 metres.
