Answer to Question #323342 in Physics for shivy

Question

A ball is tossed straight up at 24m/s. Estimate its velocity at 1s interval, and when will it reach its original starting poin

Answer 1

Given:

$v_0=24\:\rm m/s$

$g=9.8\:\rm m/s^2$

$t=1\:\rm s$

The velocity of a ball after 1s interval

$$v=v_0-gt\\ =24-9.8*1=14.2 \:\rm m/s$$
