Answer:
Distance traveled by projectile in horizontal direction will be 4.95 m
Explanation:
We have given horizontal velocity of the projectile v = 9 m/sec
We have to find the distance traveled by projectile in 0.550 sec in horizontal direction.
We know that distance is equal to multiplication of speed and time
So distance traveled in horizontal direction will be equal to
So distance traveled by projectile in horizontal direction will be 4.95 m
"Acceleration" means change of speed or direction (or both).
"Uniform velocity" means constant speed in a straight line ... no changes.
So "uniform velocity" means acceleration is zero.
