A body at rest is acted upon by two forces F1 = (40N, 045°) and
F2 = (PN, 130°).

1) Express each of the forces as a column
Vector

2) find the value of P if the magnitude
of the resultant force is 50N​

What are two different ways you could find the value of a? explain these methods.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
