Answer:
10
Explanation:
10 is the answer because you divide 50 and 5 and your answer is 10.
Hope this helps:)
Pls mark brainlist
Height increase h = R*(1 - cosΘ) = 1.2*(1-cos3.5°) = .00224 m.
<span>½Mbl*Vbl² = Mbl*g*h → </span>
<span>Vbl = √(2gh) = .2095 m/s </span>
<span>This is the initial velocity of the block. From momentum considerations, </span>
<span>Mbt*Vbt = Mbl*Vbl → </span>
<span>Vbt = (Mbl/Mbt)*Vbl = (5/.002)*.2095 = 523.8 m/s
this is what i think the answer is im not for sure though... hope it helps...</span>
Answer:
22.3Ns
Explanation:
Hi!
To solve this exercise follow the steps below.
1. Find the weight of the stone by multiplying the gravity (9.8m / s ^ 2) by the mass.
W=mg
m=mass=2.5kg
g=gravity=9.8m / s ^ 2
W=(2.5)(9.8)=25.5N
2. Find the time it takes for the stone to touch the ground using the kinematic equation for constant acceleration.
Vf=Vo+a.t
y= VoT+\frac{1}{2}gt^{2}
Where
Vo = Initial speed
=0
T = time
g=gravity=9.8m/s^2
Y= height= 3.75m
solving for time
3. For a constant force such as weight, the impulse is calculated as the product between force and time.
I=wt
I=(25.5N)(0.87S)=22.3Ns
