Just do for example on number 38 you will do 6.8/1000= 0.0068 which is the answer
1.)62
2.) 45
3.) ?
Hopefully that helps, I believe 3 is 104?
The area of the sector of a circle is expressed in the formula: A = 1/2 r^2 * theta where theta is expressed in radians. In this case, we are given with r equal to 6 inches and theta equal to pi/3. Hence the area of the sector is equal to 18.85 cm2 or 6 pi cm2.
first find the block's velocity after the collision occurs.
1/2 (1.5 + 0.00225) V^2 = 1/2 (785)(0.0588)^2
so V = 1.344 m/s
using conservation of momentum we get:
(mv)bullet + 0 = (1.50225) (1.344)
0.00225 v = 2.02
v = 2.02 / 0.00225 = 897.3 m/s
Using distance = average velocity* time t = 0.0588 / (1.344/2) = 0.0875 s
