Calculate the initial velocity of a baseball ball so you can make a home run. assume the angle that the initial speed makes with the horizontal θ=29degrees.
length of the baseball field is x=100m, height of fence is 3.5m.

35.13 m/s

Explanation:

Given

launching angle

Length of baseball field=100 m

height of fence=3.5 m

we know trajectory of projectile is given by

where y=vertical distance

x=horizontal distance

u=initial velocity

=launch angle

here y=3.5 m

x=100

u=35.13 m/s

glass has been rated on the mohs scale as 5.5

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
