I’m doing a presentation for physics class. We made rockets and my rocket flew 55 km in 3.89 s. What would be my average speed?

Sagot :

Consider that the average speed is given by:

[tex]v_{\text{avg}}=\frac{s}{t}[/tex]

where,

s: distance traveled = 55 km

t: time interval = 3.89 s

Replace the previous values of the parameters into the formula for v_avg:

[tex]v_{\text{avg}}=\frac{55\operatorname{km}}{3.89s}\approx14.14\frac{\operatorname{km}}{s}[/tex]

Hence, the average speed is approximately 14.14 km/s
