The answer for this question is 12 magnets. Hope this helps!
It will hit the ground when h(t)=0. Since the hammer is simply dropped its initial velocity, v0, is equal to zero and we are told that the initial height, h0, is 25m so our equation is:
h(t)=-4.9t^2+25, we want h(t)=0 so:
4.9t^2-25=0 add 25 to both sides
4.9t^2=25 divide both sides by 4.9
t^2=250/49, since t>0
t=+√(250/49) seconds
t≈2.3 seconds (to the nearest tenth of a second)
Answer:
y = -5/3x - 3
Assuming this is a linear function
Step-by-step explanation:
1. Use (y2-y1)/(x2-x1) to find the slope of the equation, assuming it is a linear function.
(-3-2)/(0+3) = -5/3 <--- slope
2. The y-intercept is going to be the (0, -3) point, since the point is directly on the y-axis.
3. Put both of those values into the new equation
y = -5/3x - 3
Do -104 negitiive 8 times.then you will have it.
