-- She went up for 0.4 sec and down for 0.4 sec.
-- The vertical distance traveled in gravity during ' t ' seconds is
D = (1/2) x (g) x (t)²
= (1/2) (9.8 m/s²) (0.4 sec)²
= (4.9 m/s²) x (0.16 s²)
= 0.784 meter ( B )
I took this test and the correct answer is c
I hope this helps

I want brainliest plz!!!!!
Since, A is a vector. Hence, we can break it into two components (x and y)
Angle made by the velocity vector A with the x-axis = 51.7°
Magnitude of the vector A = 70 m/s
°
m/s
°
m/s
Hence, the option C is correct.
