When you grow your brain grows its very complicated you cant just GET smart you have to learn easy stuff like 2+2 to 83x17 more you grow more your brain grows more stuff you learn but to get smarter read more do math more JUST DO EVERYTHING MORE to grow your brain and fill in your brain
Answer:
Explanation:
Ignoring air resistance
Initial vertical velocity is 30sin35 = 17.2 m/s
Gravity reduces this velocity to zero in a time of
t = v/g =17.2 / 9.8 = 1.755 s
it takes the same time to come back down to ground level for a total flight time of 2(1.755) = 3.51 s
The horizontal velocity is 30cos35 = 24.57 m/s
the distance traveled horizontally is
d = vt = 24.57(3.51) = 86.298... = 86 m
You should maintain 5-6 second driving a heavy vehicle or towing a trailer.
The purpose of driving. Driving serves many purposes. At its most fundamental level, driving a motor vehicle is a reliable, efficient and economical mode of transport.
