Question

1. with respect to non - uniform motion, w forms of the equation we used:

$a = \frac{v}{t}$ $v = a \cdot t$
$t = \frac{v}{a}$

1. perform the following conversions:

a) 5 days to seconds
432000
b) 0.364 km to meters
364 meters
c) 150km/hr to meters per second (m/s)
41.7

Explanation:

Step1: Convert days to seconds

$5 \text{ days} \times 24 \frac{\text{hr}}{\text{day}} \times 60 \frac{\text{min}}{\text{hr}} \times 60 \frac{\text{s}}{\text{min}} = 5 \times 24 \times 60 \times 60 = 432000 \text{ s}$

Step2: Convert km to meters

$0.364 \text{ km} \times 1000 \frac{\text{m}}{\text{km}} = 0.364 \times 1000 = 364 \text{ m}$

Step3: Convert km/hr to m/s

$150 \frac{\text{km}}{\text{hr}} \times \frac{1000 \text{ m}}{1 \text{ km}} \times \frac{1 \text{ hr}}{3600 \text{ s}} = 150 \times \frac{1000}{3600} \approx 41.7 \text{ m/s}$

Answer:

a) 432000 seconds
b) 364 meters
c) 41.7 m/s
