The shark can accelerate to a speed of 32.0 km/h in a few seconds. Assume that it takes a shark 1.5 s to accelerate uniformly from 2.8 km/h to 32.0 km/h. What is the magnitude of the shark's acceleration?

Answer 1

acceleration = changevelocity/time

changevelocity= 29.2km/hr*1hr/3600sec*10^3m/km=8.11m/s
