A bullet is fired at an angle of 30° to the horizontal ground at a velocity of 200 ms-1.The bullet is in flight for a time t. Air resistance has a negligible effect on the motion of the bullet. What is the correct expression for the horizontal distance R travelled by the bullet?
A. R = 200 x cos30° x t
B. R = 200 x sin30° x t
C. R=((200 x cos30°)^2)/(2x9.81)
D. R=((200 x sin 30°)^2)/(2x 9.81)
The answer is A but I have no ideas on how to get it. Help me please!
