Striking a fixed object at 60 MPH is the same as falling from a _____ story building:

speed of the striking object is given as

v = 60 mph

now this speed in SI units given as

v = 60 times frac{1609 m}{3600 s}

v = 26.82 m/s

So here we can use kinematic now to find the height from where it is dropped

so here we will have

v_f^2 - v_i^2 = 2 a d

now we have

v_f = 26.82 m/s

v_i = 0

a = 9.81 m/s^2

now from above equation

26.82^2 - 0 = 2(9.81)d

d = 36.67 m

now we know that average height of 1 story building is 3 meter

so approx total number of stories in the building will be

N = frac{36.67}{3} = 12 story
