Question

A toy rocket fired straight up into the air has height ​s(t)equals208 t minus 16 t squared feet after t seconds. a. What is the​ rocket's initial velocity​ (when tequals​0)

Answer 1

Answer:

208 ms⁻¹

Explanation:

Height h = 208 t - 16t²

differentiating this expression velocity is determined.

v = dh/dt = 208 - 32t

Initial velocity is the velocity when t = 0 .

So initial velocity = v = 208 ms⁻¹
