Question

a ball thrown with an initial velocity of (10i+15j)m/s. when it reaches the top of it trajectory, neglecting air resistance, what is velocity? what is acceleration?

Answer 1

since the apex is where vertical motion has stopped, and gravity pulls only downward,
v = 10i
a = -9.8j

Answer 2

Great
