A red ball undergoes projectile motion (position is in meters and time is in seconds). A red trail, arrows representing the velocity components, and x-y coordinates are given.
What is the speed (position given in meters and time in seconds) of the
projectile at t = 3.70 s? What is the velocity of the particle? The
acceleration is constant but not necessarily 9.8 m/s2. The scale used
to display velocity vectors is arbitrary. That is, do not assume that a vector
of length five represents a velocity of 5 m/s.
v = 15.4 m/s.
v = (8.60 i +12.8 j) m/s.
