A rock is shot straight upward with sling-shot. The intial velocity is 24.5 m/s where the downward
acceleration due to gravity is 9.81 m/s2. What is the rock'sdisplacement after 1.00 s?

Respuesta :

Answer:

Explanation:

If launch spot is origin and UP the positive direction.

s = s₀ + v₀t + ½at²

s = 0 + 24.5(1.00) + ½(-9.81)(1.00²)

s = 19.595

rounding to the 3 significant digits of the question numerals

s = 19.6 m  upward
