What is the maximum height obtained by a 125g apple that is slung from a slingshot at an angle 78° from the horizontal with an initial velocity of 18 m/s

Explanation:

As we know that the velocity of the apple is given as

at an angle of 78 degree from horizontal

so here two components of the velocity is given as

now as it rises up then due to deceleration of gravity it will slow down and finally comes to rest

so here we can use kinematics to find the maximum height

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.
