The odometer of an automobile measures the distance travelled by the vehicle. the car(b) is moving faster.
This can be explained as follows:
In order to compare the speed of both the vehicles and determine which one is moving faster, the speed of both the vehicles should be represented by the same unit.
Speed of scooter = 300 m/min
Converting this to km/hr,
Distance travelled by the scooter in 1 min= 300 m
Therefore, distance travelled by the scooter in 60min( or 1 hr ) = 18000m = 18 km
Speed of the car= 36 km/hr
Since the car travels a greater distance in 1 hr , we can say that it is moving faster.

A rock with a mass of 16 kilograms is put aboard an airplane in New York City and flown to Boston. How much work does the gravit

Law Incorporation [45]

The work done by the gravitational field of the earth on the rock is 9.998 x 10⁸ J.

<u>The given parameter include:</u>

the mass of the object, m₁ = 16 kg

Note: the mass of the earth, m₂ = 5.972 x 10²⁴ kg

The work done by the gravitational field of the earth is given as;

Work done = gravitational force (F) x radius of the earth (R)

$Work \ done = \frac{Gm_1m_2}{R^2} \times R\\\\Work \ done = \frac{Gm_1m_2}{R} \\\\where;\\\\R \ is \ the \ radius \ of \ the \ earth = 6,378 \ km = 6,378,000 \ m\\\\G \ is \ the \ universal \ gravitation \ constant = 6.674 \times 10^{-11} Nm^2/kg^2\ \\\\Work \ done = \frac{(6.674 \times 10^{-11} ) \times (5.972\times 10^{24}) \times (16)}{6,378,000 } \\\\Work \ done = 9.998 \times 10^{8} \ J$

Therefore, the work done by the gravitational field of the earth on the rock is 9.998 x 10⁸ J.
