If a car travels 30 mi. north for one-half hour, 50. mi. east for one hour, and 30 mi. south for 30 min., what is the total distance the car traveled?

110 mi

Explanation:

d1 = 30 mi, d2 = 50 mi, d3 = 30 mi

Distance is defined as the length of actual path traveled.

So, total distance, d = d1 + d2 + d3 = 30 + 50 + 30 = 110 mi

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
