A projectile is fired upward at an angle of 36.1 above the horizontal with an initial speed v, = 5.0 m/s. Write down the velocity vector v (in m/s) and the acceleration vector a (in m/s2) of the projectile at its maximum height in unit vector notationsi and j O there is no answer O v= 2i + 0j m/s, a = 0i – 10j m/s? O v= 4i + 0j m/s, a = 0i – 10j m/s? O v= 5i + 0j m/s, a = 0i + 10j m/s? v= 3i + 0j m/s, a = 0i + 10j m/s
