Question 3
A projectile is fired at an angle of 30o to the horizontal with a velocity of 40 ms-1. Calculate the velocity attained after 1s. {g = 10 ms-2]
Observation
This is another favorites question among candidates but the performance was below average. Most candidates failed to calculate the vertical and horizontal component first before using the Pythagoras theorem to evaluate the velocity.
The expected answer is:
