To solve this problem it is necessary to apply the concepts related to the conservation of the Momentum describing the inelastic collision of two bodies. By definition the collision between the two bodies is given as:
![m_1v_1+m_2v_2 = (m_1+m_2)V_f](https://tex.z-dn.net/?f=m_1v_1%2Bm_2v_2%20%3D%20%28m_1%2Bm_2%29V_f)
Where,
= Mass of each object
= Initial Velocity of Each object
= Final Velocity
Our values are given as
![m_1 = 2190Kg](https://tex.z-dn.net/?f=m_1%20%3D%202190Kg)
![v_1 =10.5m/s](https://tex.z-dn.net/?f=v_1%20%3D10.5m%2Fs)
![m_2 = 3220kg](https://tex.z-dn.net/?f=m_2%20%3D%203220kg)
![V_f = 4.74m/s](https://tex.z-dn.net/?f=V_f%20%3D%204.74m%2Fs)
Replacing we have that
![m_1v_1+m_2v_2 = (m_1+m_2)V_f](https://tex.z-dn.net/?f=m_1v_1%2Bm_2v_2%20%3D%20%28m_1%2Bm_2%29V_f)
![(2190)(10.5)+(3220)v_2 = (2190+3220)(4.74)](https://tex.z-dn.net/?f=%282190%29%2810.5%29%2B%283220%29v_2%20%3D%20%282190%2B3220%29%284.74%29)
![v_2 = 0.8224m/s](https://tex.z-dn.net/?f=v_2%20%3D%200.8224m%2Fs)
Therefore the the velocity of the 3220 kg car before the collision was 0.8224m/s
The units for mass are grams (g) and kilograms (kg)
the units for volume are millilitres (ml) and litres (l)
Answer:
gravity
Explanation:
as the earth rotates on an axis, it causes an effect known as centripetal acceleration with is an acceleration that pulls objects towards the center of the object. in planets, we call this Gravity
Answer:
0.8214 m/s^2
Explanation:
Fnet= Fpushed - Ffriction
Fpushed = 12.7N Ffriction = 8.33N
Fnet = 12.7N - 8.33N = 4.37N
Fnet= mass(acceleration)
Fnet = 4.37N mass = 5.32 kg
4.37N = 5.32 kg(acceleration)
acceleration= 0.8214 m/s^2
