Answer:
s = 400 ft
The maximum height reached by the ball is 400 ft
Explanation:
Given;
Initial vertical velocity v = 160 ft/s
Height function s = 160t - 16t^2 ......1
The maximum height is reached when the change in height with respect to time is zero.
ds/dt = 0
Differentiating the height function;
ds/dt = 160 - 32t = 0
160 - 32t = 0
Solving for t;
32t = 160
t = 160/32
t = 5 seconds
Therefore, the maximum height is at t = 5;
Substituting into equation 1 (the height function)
s = 160(5) - 16(5^2)
s = 800 - 400
s = 400 ft
The maximum height reached by the ball is 400 ft
I can barely see the image you put
Answer:
Explanation:
Power Dissipated in a resistor is given by two methods i.e.
and
where 
both formula gives Power but Former is used when voltage is constant i.e. when resistors are in parallel and the later is used when the resistor are in series .
Though can also be used in series but we have to calculate the Potential drop across each resistor then we can apply the formula.
Similar is with 
First we have to calculate current through each resistor then we can apply the Formula
Answer:
Newtons second law of motion relates to force, inversely related to its <em><u>mass</u></em><em> </em>and acceleration.
