Consider the wave function y(x)-Find the probability of fi in the range -a

Lera25 [3.4K]

Answer: $(y(x))^{2}$

Explanation:

The probability of fi in a range is given by the integral, whose limits are the range limits, of the square of the wave function y(x).

Example:

let's say range [a,b] with wave function y(x), then

$Prob(a\leq x\leq b)=\int\limits^b_a {y(x)^{2} } \, dx$

At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball

Ymorist [56]

Answer:440.03 N

Explanation:

Given

horizontal component of acceleration $(a_x)=800 m/s^2$

vertical component of acceleration $(a_y)=880 m/s^2$

mass of ball =0.37 kg

Force in horizontal direction $=m\times a_x=0.37\times 800=296 N$

Force in vertical direction $=m\times a_y=0.37\times 880=325.6 N$

Therefore net force is

$F=F_x+F_y$

$|F|=\sqrt{296^2+325.6^2}$

|F|=440.03 N
