Answer:
t=usin30/g
=10×1/2×10
=1/2 sec
malik2002:
at which time velocity and acceleration is perpendicular
1/2 sec
but how
according to formula
but how u know that vel and acc are perpendicular
at this time
because this formula used for time taken to reach at half of total distance...and we know that...velocity and accelration is perpendicular at this point...velocity is horizontal and accelration is downward...
pls mark me as brainliest
