Question

speed of 15m/s. How high will it go before it begins to fall downwards (take g=10m/s square)

Answer 1

Answer: 11.25m

Explanation:

${maximum \: height} = \frac{ {u}^{2} }{2g} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ {15}^{2} }{2 \times 10} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{225}{20} = 11.25m$
