Answer:
2.1 m/s
Explanation:
According to law of conservation of momentum;
m1u1 + m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v is the common velocity
Given
m1 = 2150kg
m2 = 3250kg
u1 = 10.0m/s
u2 = ?
v = 5.22m/s
Substitute and get u2
2150(10) + 3250u2 = (2150+3250)5.22
21,500 + 3250u2 = 5400(5.22)
3250u2 = 28,188 - 21500
3250u2 = 6688
u2 = 6688/3250
u2 = 2.1 m/s
Hence the 3250 kg car’s initial velocity has an initial velocity of 2.1 m/s
Explanation:
<em>an </em><em>eclipse </em><em>happens </em><em>when </em><em>one </em>
<em>astronomical </em><em>body </em><em>block </em><em>light </em>
<em>from </em><em>or </em><em>to </em><em>another</em><em>,</em><em> </em><em>the </em><em>moon </em><em>moves </em><em>into</em>

As the car is moving it indicates that the kinetic energy is being represented. That's why I am pretty sure that this statement is correct! That's all you need to know to solve this. Regards!
Explanation:
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .
