Question

all ball is thrown vertically upward at an initial velocity 23m/s what is the displacement of ball 3 sec after its thrown​

Answer 1

Answer:24m

Explanation...hi there

We know the eq s=ut+1÷2at^2

Since gravity is acting in the down ward direction we can take it as negative ......u is positive bcoz its in the upward direction

So

S=ut-1÷2gt^2

=23×3-1÷2×10(aprox)×9

=24

Hope it helps
