(4%) Problem 5: Consider the kinetic energy of a 21500-kg truck moving at 105 km/h and that of an 87.5-kg astronaut in orbit moving at 27500 km/h What is the ratio of the kinetic energy of the truck to the kinetic energy of the astronaut?

Step 1
Given that the mass of the truck is 22500 grams, we need to convert it to kilograms by dividing it by 1000. 22500 grams ÷ 1000 = 22.5 kilograms Show more…
