Question

Sam tosses a 0.06 kg ball horizontally with an initial velocity of 10.0 m/s.

a) What is in m/s the horizontal velocity of the ball 0.50 seconds after it was tossed? (assume |g| =10 N/kg)

b) What is in m/s the vertical velocity of the ball 0.50 seconds after it was tossed? assume |g| =10 N/kg)

c) What is in m/s2 the horizontal component of the acceleration of the ball 0.50 seconds after it was tossed? (|g| =10 N/kg)

d) What is in m/s2 the vertical component of the acceleration of the ball 0.50 seconds after it was tossed? (assume |g| =10 N/kg)

Part A)

Velocity in the x direction does not change since gravity only acts in the vertical

Thus it will still be 10 m/s

Part B)

Gravity plays a part here and it started off with no initial vertical velocity

vf = vo + at

vf = 0 + (-10)(.5)

vf = -5 m/s (The negative indicates the downward direction)

Part C)

0 m/s2 because gravity only acts vertically

Part D)

-10 m/s2 (Again negative only indicates direction is downward)
