Explanation:
According to the table,
Speed of Boat
= 
Now,

Answer:
v2f = +15.8 m/s
Explanation:
Conservation law of linear momentum:
m1v1i + m2vi2 = m1v1f + m2v2f
Given:
m1 = 1.1 × 10^3 kg
m2 = 2.3 × 10^3 kg
v1i = +22.0 m/s
v2i = 0
v1f = -11.0 m/s
v2f = ?
Re-arranging the conservation law, we get
m1v1i = m1v1f + m2v2f
Solving for v2f,
m2v2f =m1(v1i - v1f)
or
v2f = m1(v1i - v1f)/m2
= (1.1 × 10^3 kg)(22.0 m/s - (-11.0 m/s))/(2.3 m/s)
= (1.1 × 10^3 kg)(33.0 m/s)/(2.3 × 10^3 kg)
= +15.8 m/s
The magnitude of v⃗ is {sqrt(m1v1)2+(m2v2)2/ m1+m2}, that is, the speed v of the two-car unit after the collision.
<h3>What is
collision?</h3>
- In physics, collisions occur when particles, aggregates of particles, or solids come close to each other, interact and affect each other.
- Collisions are of three types Fully elastic collision, inelastic collision and Perfectly inelastic collision.
- Multiply the mass of the second object by its velocity.
- For example, if the weight is 1,000 and the speed is -30 meters per second, then its momentum is 30,000 kg meters per second.
- Add the two velocities together to determine the direction the object will move after a collision.
- So the formula for determining the size of a vector (in 2D space) is v = (x, y).|v| = √(x2 + y2).
- This formula is derived from the Pythagorean theorem.
- The formula V = (x, y, z) that determines the size of a vector (in 3-dimensional space) is:|V| = √(x2 + y2 + z2)
