a bicycle and its circle move at a speed of 5 m/s downslope if the kinetic energy of the bike and the ride is 750 j what is their combined mass​

Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The kinetic energy of a moving object is given by

[tex]\boxed{KE = \frac{1}{2}mv^{2}}[/tex]

where:

KE = kinetic energy

m = mass

v = speed

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for m

[tex]KE = \dfrac{1}{2}mv^{2}[/tex]

[tex]2KE = mv^{2}[/tex]

[tex]m = \dfrac{2KE}{v^{2}}[/tex]

[tex]m = \dfrac{2(\text{750 J})}{(\text{5 m/s})^{2}}[/tex]

[tex]\boxed{m = \text{60 kg}}[/tex]

Therefore, the combined mass is 60 kg.
