Ahome run is hit in such a way that the baseball just clears a wall 20.0 m high, located 114 m from home plate. the ball is hit at an angle of 33.0° to the horizontal, and air resistance is negligible. (assume that the ball is hit at a height of 1.0 m above the ground.) (a) find the initial speed of the ball. incorrect: your answer is incorrect. write the expressions for the horizontal and vertical positions as functions of time. then use the equations to find the initial speed and the time when the baseball reaches the height of interest. m/s

Explanation:

Let the initial speed of the ball is given as

then angle of inclination is given as 33 degree

now its two components of velocity is given as

now the two positions with time given as

now when it hit the wall so we will have

now from above two equations we will have

now from above equations again

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
