Remark
This is a momentum question. Both cars are sitting still (v1 and v2 are both 0) to start with). When the spring is sprung), they both move but in opposite directions.
Let us say that v4 is minus.
Equation
0 = m3*v3 - m4* v4
Givens
m3 = 1750 kg
m4 = 1000 kg
v3 = 4 m/s
Solution
m3*4m/s - m4*x = 0
1750 * 4 - 1000*x = 0
1750 * 4 = 1000x
7000 = 1000 x
7000/1000 = x
x = 7 m/s

Hey :)
Weight is the force acting on the object due to gravity.
Mass is the measure of the quantity of matter that a body or an object contains
Hope this helps :)
Answer:
Explanation:
Given
--- Wavelength
--- Period
Required
Determine the velocity of the wave
This is calculated using:
<em>Hence, the velocity is 0.25m/s</em>
acceleration is considered to describe an increase or positive change of speed or velocity But deceleation is considered to describe a decrease or negative change of speed or velocity
