Question

e. A ball falls off a table and reaches
the ground in 1 s. Assuming g = 10
m/s. calculate its speed on reaching
the ground and the height of the
table.​

Answer 1

Answer:

Rounded shoulders are typically caused by poor posture habits, muscle imbalances and focusing too much on certain exercises, such as too much focus on chest strength while neglecting the upper back. Exercises to strengthen your core, upper back and chest muscles will help correct rounded shoulders: plank. bridges.

Answer 2

Answer:

INITIAL VELOCITY OF THE BALL=O M/S

TIME TAKEN=1S

ACCELERATION DUE TO GRAVITY=10M/S^2

SO TO FIND HEIGHT (DISTANCE):

$s = ut + \frac{1}{2} g {t}^{2}$

$s = 0 + 5 \times 1 \\ \\ = s = 5m$

NOW TO FIND FINAL VELOCITY:

$v = u + gt \\ \\ = v = 0 + 10 \\ \\ = v = 10m {s}^{ - 1}$
