Question

1. Ball thrown at 30° with intial velocity of 20m/s.

Find the

A. Initial velocity

B. Final velocity

C. Acceleration (m/s²)

D. Time ( s )

E. Distance ( m )

Answer 1

$\text{ A.}\space v_i=20\text{ m/s}.\\ \text{ B.}\space v_f=20\text{ m/s}.\\ \text{ C.}\space g=9.8\text{ m/s}^2.\\ \text{ D.}\space t=2v\sin\theta/g=2\text{ s}.\\ \text{ E.}\space D=v\cos\theta·t=34.6\text{ m}.\\$
