Answer:
12.45kgm/s
Explanation:
1.27kg x 9.8m/s = 12.446kgm/s
The sum of decimal point is 3 and the unit kg multiplies m divided by s
Answer:
88.1 N
Explanation:
As shown in the free body diagram attached to the question, the only forces acting on the inner block include in the required vertical direction.
- Its Weight.
- Frictional forces as a result of the Two compression forces.
If the block is not to slip off, the weights must match the two frictional forces
Let the compressive forces be F and frictional force be Fr
Fr = μ F
Sum of force acting on the inner block in the y-direction
Fr + Fr - W = 0
μ F + μ F = mg
2 μF = 118
2(0.67) F = 118
F = 118/1.34
F = 88.1 N
Each of the compression forces is 88.1 N
Hope this Helps!!!
<span>When a force is applied to an object for an amount of time, it is known as Impulse.</span>
Answer:
high frequent sound
Explanation:
because if its low than its slower.
(a) work=Fd
<span>345x24=8280J </span>
<span>(b) work=Force of friction*d </span>
<span>Force of friction =coefficient*normal force=.22x1.5x10^3=330 </span>
<span>330*d=7920J </span>
<span>(c) net work =8280-7920=360J</span>
