If you are driving down the highway and a bug splatters on your windshield which undergoes the greatest change in momentum during the time of contact? momentum is the same!
Answer:
4.08 kg
Explanation:
We can apply the Newton's second law of motion to find the mass of this object:
,
where
is mass, and
is acceleration, which is substituted by
here. Now, plugging given numbers in the equation, we have
.
Solving for mass, we have

Answer:
v = 29.73[m/s]
Explanation:
Kinetic energy is defined by the following equation:
![E_{k}=\frac{1}{2}*m*v^2 \\199=0.5*0.45}*v^2\\v=\sqrt{\frac{199}{0.5*0.45} }\\ v= 29.73[m/s]](https://tex.z-dn.net/?f=E_%7Bk%7D%3D%5Cfrac%7B1%7D%7B2%7D%2Am%2Av%5E2%20%5C%5C199%3D0.5%2A0.45%7D%2Av%5E2%5C%5Cv%3D%5Csqrt%7B%5Cfrac%7B199%7D%7B0.5%2A0.45%7D%20%7D%5C%5C%20v%3D%2029.73%5Bm%2Fs%5D)
