A projectile is launched at an angle to the horizontal at time t = 0. It travels over horizontal ground, as shown. Air resistance is negligible. Which graph best shows the variation with t of the speed of the projectile from when it is launched to when it lands on the ground?

1. AGraph A: speed constant (horizontal line)
2. BGraph B: speed decreases linearly to zero then increases linearly
3. CGraph C: speed decreases to a minimum then increases (curved)
4. DGraph D: speed decreases to zero then increases (curved)
