Question

*medal to correct*A projectile is launched at a 40 degree angle . At the top of its motion, what is true?

Answer 1

@ganeshie8 hello! could u answer/explain this short question? Would it be -9.8 acceleration and 0 Vy (velocity of y component) then why is it -9.8 acceleration??

Answer 2

A. v = 0 m/s, a = 0 m/s^2
B. v_x = 0 m/s, a = 0 m/s^2
C. v_y = 0 m/s, a = -9.8 m/s^2
D. v = 0 m/s, a = -9.8 m/s^2

Answer 3

Acceleration is always g and downward, if we ignore air drag.

Answer 4

g is never 0, when u r near by earth

Answer 5

also, v_x remains fixed during the flight as there is no acceleration in x direction
