Question 16 in last years paper:
A projectile is fired at a velocity of 50 m/s at an angle of 30° to the horizontal.
Determine the range of the projectile. 4 Marks.
This is how i answered it:
v = u + at
0 = 50 -9.8t
t = 5.1 seconds
Range = horizontal velocity x time of flight
= 50cos30 x 5.1
= 220.9 metres
Is this correct? If not, how do i go about it?
Thanks in advance
