Quinn is testing the motion of two projectiles x and y by shooting them from a sling shot. What can we say best describes the motion of the projectiles ? Assume air resistance is not a factor
Answer
A
The horizontal velocity of projectile X is changing, and the vertical velocity of projectile Y is constant.
B
The vertical velocity of projectile Y is changing, and the horizontal velocity of projectile X is constant.
C
The horizontal acceleration of projectile X is –9.8 m/s2, and the vertical acceleration of projectile Y is 0 m/s2.
D
The horizontal acceleration of projectile Y is –9.8 m/s2, and the vertical acceleration of projectile Y is 0 m/s2.
