A pilot flies with a constant speed of 120km/h relative to the air, and makes instantaneous turns, when necessary. He follows a perfectly square path on the ground, using north-south and east-west roads as a guide for each of the 60km sides. On a daywhen there is a steady 60km/h wind blwoing...
if he were to swim across and there is no current his time would be 107.5s
so could i just plug that to find the velocity of the current
v=d/t
= 54/107.5
=0.50m/s
can i do that
A swimmer who can swim at a speed of 0.8 m/s in still water heads directly across a river 86m wide. the swimmer lands at a position on the far bank 54m downstream from the starting point. determine:
a) the speed of the current
b) velocity of swimmer relative to the shore
c) the direction of...
well this is what i have,
d=vt - 1/2at^2 and i believe i should find the time it takes
a= 0.9m/s^2 = 3.24km/h^2
Train 1
1.2 = 100t - 1/2(3.24)t^2
0= -1.2 + 100t - 1.62t^2
then i use the quadratic eqn to solve for t. am i on the...
hi I am new to this and i have a problem that I am stumped on.
Two trains, one traveling at 100km/h and the other at 128km/h, are headed towards one aanother along a straight level track. When the trains are 1.2km apart, each engineer sees the other train and applies the brakes. Both trains...
