A 64-kg skater initially at rest throws a 5.0-kg medicine ball horizontally to the left. Suppose the ball is accelerated through a distance of 1.0 m before leaving the skater's hand at a speed of 7.0 m/s . Assume the skater and the ball to be point-like, the surface to be frictionless, and ignore air resistance. Use a vertical y-axis with the positive direction pointing up, and a horizontal x-axis with the positive direction pointing to the right.
A) Determine the acceleration of the ball during the throw.
B) Determine the acceleration of the skater during the throw.

the answer is 3.1 his answer is wrong mines is right

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
