V=f*lambda .. so make lambda the subject.. Lambda is equal to V/ F ... the answer is 6.66*10^3. I converted km to meters
Answer:
Its not A..
Explanation:
I chose A - was incorrect
Your answer is.. 22000 mg = 2200 cg
Because:
1 mg = 0.1 cg
I hope this helps!
Answer:
13.309 m/s²
Explanation:
Length from shoulder to hand, l = 30 cm = 0.3 m
initial velocity, u = 1 m/s
final velocity, v = 2.5 m/s
time, t = 3 s
Let the tangential acceleration is a.
by using first equation of motion
v = u + at
2.5 = 1 + 3 a
a = 0.5 m/s²
Let the centripetal acceleration is a'.
a' = v'²/l
a' = 2 x 2 / 0.3
a' = 13.3 m/s²
The tangential acceleration and the centripetal acceleration are both perpendicular to each other. So, the net acceleration is given by
A = 13.309 m/s²
