Question

Rex Things throws his mother's crystal vase vertically upwards with an initial velocity of 26.2 m/s. Determine the height to which the vase will rise above its initial height.

Answer 1

Answer:

35.0 m to the nearest tenth.

Step-by-step explanation:

We can use  one of the equations of motion for constant acceleration:

v^2 = u^2 + 2gs    where v = final velocity, u = initial velocity , g = acceleration due to gravity and s = height above initial height.

As the motion is against gravity g will be negative:

V = 0 (at final height), u = 26.2, g = -9.81:

0 = 26.2^2 + 2 * -9.81 * s

s = - (26.2)^2 / (-2*9.81)

s = 35.0 m to the nearest tenth.
