170-68 = 102 meters to catch the antelope
from a) 1 stride = 7 meters in 0.28 seconds
102/7 = 14.57 strides x 0.28 = 4.08 seconds total
V=D/T = 102/4.08 = 25 meters/second
1m/s = 3.6 K/H
25 x 3.6 = 90 Kilometers/ hour
Answer:
Mass (m) = 5.4 kg
Force (f) = 20 N
Acceleration (a) = ?
Acceleration= m × a
=> The resulting acceleration of the object is <u>1</u><u>0</u><u>8</u><u> </u><u>m/</u><u>s²</u><u>.</u>
Answer: Can I get a picture???
Answer:
TRUE
Explanation:
It is TRUE that pedestrians, bicyclists and slow-moving vehicles are not allowed on expressways because expressways have minimum speed limit requirements that these travelers cannot reach. This minimum limit of speed varies country to country.
In America, the minimum speed limit <u>in Rural Areas is 40 mph (miles per hour) i.e. 65km/h</u> (kilometer per hour) while <u>in Urban Areas it is 55mph i.e. 90km/h</u> which cannot be met by pedestrians and by-cycles easily.
