Asked by Katrina
A projectile was launched from the ground with a certain initial velocity. Militaries used a radar to determine the vertical coordinate y(t) of the projectile for two moments of time t measured in seconds from the moment when the projectile was launched. The radar measurements showed that y(2)=269 meters,y(5)=565 meters. Calculate the maximum of y(t) if it is known as follows:
The projectile was moving along a vertical line.
The acceleration due to gravity g is 9.81 meter/〖second〗^2.
There is a resistance proportional to the velocity of the projectile.
The value of the empirical coefficient ρ is a constant.
Distances are measured in meters.
