Question

7 if a rocket travels 1000 km west for 1 hour, what is its velocity? 1000km/hr w 500 km/hr w 250 km/hr w orange green yellow 8 a swimmer swims for 2 kilometers north in a time period of 1 hour. what is the velocity? 2 km/hr n 2 km/hr 2 km/hr s blue blue purple

Explanation:

Problem 7 (Rocket Velocity)

Step1: Recall Velocity Formula

Velocity is defined as displacement divided by time, \( v = \frac{d}{t} \), where \( d \) is displacement (with direction) and \( t \) is time.

Step2: Identify Displacement and Time

Displacement \( d = 1000 \) km West, time \( t = 1 \) hour.

Step3: Calculate Velocity

Substitute into the formula: \( v = \frac{1000\ \text{km West}}{1\ \text{hr}} = 1000\ \text{km/hr West} \).

Step1: Recall Velocity Formula

Velocity \( v = \frac{d}{t} \), with displacement \( d \) (including direction) and time \( t \).

Step2: Identify Displacement and Time

Displacement \( d = 2 \) km North, time \( t = 1 \) hour.

Step3: Calculate Velocity

Substitute: \( v = \frac{2\ \text{km North}}{1\ \text{hr}} = 2\ \text{km/hr North} \).

Answer:

Orange (1000km/hr W)
