Question

The thunderbolt bobsled team is training for Olympic Gold. During practice they start a run with a speed of 0.57 m/s, they complete the 1360 m run in 89.49 seconds. What is the acceleration of the sled?

Answer 1

$acceleration=\frac{\Delta\ velocity}{\Delta\ time}\\\\ v_{initial}=0,57m/s\\ distance=1360m\\ \Delta\ time=89,49seconds\\\\ v_{final}-v_{initial}=\frac{distance}{time}\\ v_{final}=\frac{distance}{time}+v_{initial}\\ v_{final}=\frac{1360}{89,49}+0,57\\\\v_{final}=15,77\frac{m}{s}\\\\ acceleration=\frac{15,77-0,57}{89,49}=0,17\frac{m}{s^2}\\\\ \boxed{acceleration=0,17\frac{m}{s^2}}$
