Question 214191: A particle starts from the origin at t = 0 with
an initial velocity having an x component of
17.7 m/s and a y component of −10.8 m/s.
The particle moves in the xy plane with an
x component of acceleration only, given by
4.51 m/s2.
a. Determine the x component of velocity af-
ter 7.16 s. Answer in units of m/s. 49.9916 m/s
b. Find the speed of the particle after 7.16 s.
Answer in units of m/s.
c. Find the magnitude of the displacement vec-
tor of the particle after t = 7.16 s. Answer in
units of m.

A particle starts from the origin at t = 0 with
an initial velocity having an x component of
17.7 m/s and a y component of −10.8 m/s.
The particle moves in the xy plane with an
x component of acceleration only, given by
4.51 m/s2.
a. Determine the x component of velocity af-
ter 7.16 s. Answer in units of m/s. 49.9916 m/s
------------------------
b. Find the speed of the particle after 7.16 s.
Answer in units of m/s.
x & y are respective speeds
v =~ 51.145 m/sec
------------------
c. Find the magnitude of the displacement vec-
tor of the particle after t = 7.16 s. Answer in
units of m.
x = 7.16*(17.7 + 49.9916)/2
x = 242.34 meters
------
y = - 7.16*10.8
y = 77.328 meters
s = 254.375 meters
