30x30=900
You just multiply 3x3 first and then you add the zeros left.

Answer: 25m/s

Explanation:

$S1=(2u+v)t \\ =20×20=400m \\ S2=40×20=800m \\ S3=(2u+v)t \\ =20×40=800m \\ Total \: displacement =2000 m \\ Total \: time \: taken =80 m \\ V=802000=25m/s$

Can someone please give me the answer to the second part of this question?<br> Thank You!

Answer:

$\theta=30\textdegree$

Step-by-step explanation:

$(ii)\ \sqrt{3}\tan\ \theta=2\sin \theta\\\\substitute\ \tan\theta=\frac{\sin\theta}{\cos\theta}\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta}=2\sin\theta\\\\Divide\ both\ sides\ by\ \sin\theta.\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta\times \sin\theta}=\frac{2\sin\theta}{\sin\theta}\\\\\frac{\sqrt{3}}{\cos\theta}=\frac{2}{1}\\\\Apply\ cross\ multiplication\\\\2\cos\theta=\sqrt{3}\\\\divide\ both\ sides\ by\ 2\\\\\frac{2\cos\theta}{2}=\frac{\sqrt{3}}{2}\\\\\cos\theta=\frac{\sqrt{3}}{2}\\\\$
