Answer:
mouse speed is 5 m/s
Explanation:
given data
belt roll b = 3 m/s
head straight h = 4 m/s
to find out
mouse speed s
solution
we will apply here pythagorean theorem
that is
s = [tex]\sqrt{b^{2} +h^{2} }[/tex] ...........................1
put here value in equation 1 as b = 3 and h = 4
so
s = [tex]\sqrt{b^{2} +h^{2} }[/tex]
s = [tex]\sqrt{3^{2} +4^{2} }[/tex]
s = [tex]\sqrt{9 + 16 }[/tex]
s = [tex]\sqrt{25 }[/tex]
s = 5
so mouse speed is 5 m/s
