    Help on Kinematics: Trip Time Calculation w/ 60km/h Wind

    he has a constant velocity of 120km/h but with wind affecting him he's not aligned?

    Help on Kinematics: Trip Time Calculation w/ 60km/h Wind

    when add all the legs together i get 1.48h. the answer is 2.5h whats wrong here.

    Help on Kinematics: Trip Time Calculation w/ 60km/h Wind

    So for the north it would be 120km/h + 42.43km/h = 162.43km/h t = d/t = 60/162.43 = 0.37h?

    Help on Kinematics: Trip Time Calculation w/ 60km/h Wind

    ok i found the x and y components they are both 42.43m/s. what do you mean by leg?

    Help on Kinematics: Trip Time Calculation w/ 60km/h Wind

    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...

    Kinematics Problem: Speed of Current, Velocity, Direction

    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

    Kinematics Problem: Speed of Current, Velocity, Direction

    the current moved him 54m down the stream hwo would i get the time what do you mean by a component of his total distance?

    Kinematics Problem: Speed of Current, Velocity, Direction

    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...

    What is the final distance between two decelerating trains on a straight track?

    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...

    What is the final distance between two decelerating trains on a straight track?

    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...
