Option B: 4.0 cm is the value of w
Explanation:
It is given that ,
,
and
Using the law of sines, we have,
Substituting the values, we have,
Cross multiplying, we get,
Simplifying, we have,
Dividing both sides by 0.515, we have,
Thus, the value of w is 4.0 cm
Hence, Option B is the correct answer.
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
Where
s is the distance covered
t is the time
Hence, this is the required solution.
