Please help im being timed A baseball is hit at an initial speed of 40 m/s at an angle of 60° above the horizontal. Find the ball’s maximum height in meters. Use g = 9.81 m/s2.
A
10.2

B
20.4

C
22.4

D
61.2

7.06 m

Explanation:

As we know that ,

→ h = u²sin²∅/2g

→ h = 40 * 40 * sin² 60° / 2 * 9.81

→ h = 40 * 40 * √3 / 2 * 2 * 9.81

→ h = 7.06 m

  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

conservation of mass

mass before something happens = mass afterwards
