Harman [31]

Answer: 1.9 m/s

Explanation:

1) Data:

height, y = 0

range, x = 0.77m

angle, α = 45°

question, horizontal velocity, Vox = ?

2) Physical principles and formulas

Projectile motion.

$y=V_{0y}t-gt^{2} /2\\ \\ x=V_{0x}t\\ \\ V_{0y}=V_0sin\alpha \\ \\ V_{0x}=V_0cos\alpha$

3) Solution

$0.77=V_0cos(45)t\\ t=0.77/(V_0cos(45))$

$y=0=V_0sin(45)t-gt^{2} /2$

Factor

$0=t[V_0sin(45)-gt/2]$

Discard t = 0 and solve for the other factor:

$gt/2=V_0sin(45)\\ \\ V_0= gt/(2sin(45))=9.81[0.77/V_{0}cos(45)]/[2sin(45)]\\ \\ V_0^2=9.81[0.77/(2cos(45)sin(45)=9.81[0.77/sin(90)]=7.55\\ \\ V_0}=\sqrt{7.55} =2.8$

Find Vx:

$Vx=V_{0x}=V_{0}cos(45)=2.75(\sqrt{2} /2]=1.9$

Vx = 1.9m/s ← answer
