Answer:
0.26seconds
Explanation:
Impulse is the product of force and time
Impulse =Force * Time
Given
Impulse = 67Ns
Force = 257N
Required
Time
From the formula;
Time = Impulse/Force
Time = 67/257
Time = 0.26s
Hence the amount of time is 0.26seconds

answer is friction. MCQ A is answer
Answer:
77.88 lbm/ft³
Explanation:
Given,
Specific gravity, SG = 1.25
Density of water, ρ = 62.30 lbm/ft³
density of the fluid =
= S.G x ρ_{water}
= 62.30 x 1.25
= 77.88 lbm/ft³
Density of the fluid is equal to 77.88 lbm/ft³
Answer:
velocity of combined objects is 6 m/s
Explanation:
As per law of conservation of momentum
total momentum before collision = total momentum after collision
since the two objects sticks together after collision so we will have

Now plug in all values in it




so the missing value in the table is velocity which is 6 m/s
