Due to the conservation of linear momentum:
p (before) = p (after)
m1u1 + m2u2 = m1v1 + m2v2
0.013*213 + 2*0 = 0.013*152 + 2.0*v
2.769 = 1.976 + 2v
2v = 0.793
v = 0.397ms-1
Answer:
t=3.0289s (Assuming a=9.81)
t=3s (Assuming a=10)
Explanation:
a=9.81
u=0
s=45
t = 3.0289s
A "derived unit" is a specific combination of base units with its own name. <em>(3)</em>
Examples:
<u>Combination of base units</u> <u>Its own name</u>
kilogram-meter / second² Newton
Coulomb / second Ampere
kilogram-meter² / second² (Newton-meter) Joule
kilogram-meter² / second³ (Joule / sec) Watt
