Determine the weight of the bus in Newtons. weight = mass × acceleration due to gravity (g) g = 9.8 m/s 2 A blue whale is 30 m long and has a mass of 40,000 kg (400 metric tons). Calculate the weight of a blue whale in Newtons weight = mass × acceleration due to gravity (g) g = 9.8 m/s 2 Acceleration is force divided by mass. acceleration = force/mass If a force of 10 N is applied to a 2 kg object, the object will accelerate at _______ m/s 2 .
