Question

Calculate the displacement and velocity at times of (a) 0.500 s, (b) 1.00 s, (c) 1.50 s, and (d) 2.00 s for a ball thrown straight up with an initial velocity of 15.0 m/s. Take the point of release to be y0=0.

a) (a) Displacement = 6.25 m, Velocity = -5.0 m/s; (b) Displacement = 15.0 m, Velocity = -10.0 m/s; (c) Displacement = 33.75 m, Velocity = -15.0 m/s; (d) Displacement = 60.0 m, Velocity = -20.0 m/s
b) (a) Displacement = 3.75 m, Velocity = -7.5 m/s; (b) Displacement = 22.5 m, Velocity = -12.5 m/s; (c) Displacement = 48.75 m, Velocity = -17.5 m/s; (d) Displacement = 82.5 m, Velocity = -22.5 m/s
c) (a) Displacement = 5.0 m, Velocity = -2.5 m/s; (b) Displacement = 12.5 m, Velocity = -5.0 m/s; (c) Displacement = 27.5 m, Velocity = -7.5 m/s; (d) Displacement = 50.0 m, Velocity = -10.0 m/s
d) (a) Displacement = 2.5 m, Velocity = -10.0 m/s; (b) Displacement = 17.5 m, Velocity = -15.0 m/s; (c) Displacement = 37.5 m, Velocity = -20.0 m/s; (d) Displacement = 62.5 m, Velocity = -25.0 m/s

Answer 1

The displacement and velocity of a ball thrown straight up at different times can be calculated using its initial velocity. The correct answer is option A.

Step-by-step explanation:

When a ball is thrown straight up with an initial velocity of 15.0 m/s, its displacement and velocity can be calculated at different times.

At t = 0.500 s, the displacement is 6.25 m and the velocity is -5.0 m/s.

At t = 1.00 s, the displacement is 15.0 m and the velocity is -10.0 m/s.

At t = 1.50 s, the displacement is 33.75 m and the velocity is -15.0 m/s.

At t = 2.00 s, the displacement is 60.0 m and the velocity is -20.0 m/s.
