Answer:
it should be -2m/s
Explanation:
Because it is going down from minutes 6-8. And down in most cases means negative. And since it is going down 2 it should be -2m/s.

When a vehicle changes direction, its velocity also changes since velocity comprises both speed and direction.
<h3>How do you calculate final velocity?</h3>
V f is equal to V i plus At. The final velocity of an item can be calculated for a given beginning velocity by multiplying the acceleration brought on by a force by the time the force is applied and then adding the result to the initial velocity.
<h3>What is the collision formula?</h3>
An elastic collision is one in which the momentum, p, and the kinetic energy, KE, are both conserved. In other words, po = pf and KE0 = KEf are the results. We will write 1/2 m1 when we remember that KE = 1/2 mv2 (v1i) 2 + 1/2 m2(vi) (vi) 2 is equal to half of m(v1f) and m(v2f).

Answer:
24 cm/s
Explanation:
Applying
Pythagoras theorem,
a² = b²+c²............. Equation 1
Where a = resultant, b = vertical component, c = horizontal component
From the question,
Given: a = 26 cm/s, c = 10 cm/s
Substitute these values into equation 1
26² = b²+10²
676 = b²+100
b² = 676-100
b² = 576
b = √576
b = 24 cm/s
