1)A vector that is 1 cm long represents a displacement of 17 km. How many kilometers are represented by a 23-cm vector drawn to the same scale?
2)A descent vehicle landing on Mars has a vertical velocity toward the surface of Mars of 6.5 m/s. At the same time, it has a horizontal velocity of 2.5 m/s.
A)At what speed does the vehicle move along its descent path?
B)At what angle with the vertical is this path?
3)
(a) Find the x and y components of a position vector, r, of magnitude r = 87 m, if its angle relative to the +x axis is 50.0°.
(b) What if the relative angle is instead 55.0°?

1) 391 km
2a 6.964 m/s
2b 21 degrees
3a y comp 66.64 m x is 55.92
3b is y is 71.26 and x is 49.90
With 87 being your hyp. 87^2 should be equal to your sides squared which it is you can check x and y components with the patagrem theron
