(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A projectile is fired across a horizontal flat plane. Its initial velocity is 25.5 m/s and is fired at an angle of 31.8° above the horizontal

(a) How long does it take to get to the maximum height?

(b) What is the maximum height?

(c) Determine the horizontal and vertical components of the velocity vector at the maximum height.

(d) Determine the horizontal and vertical components of the acceleration vector at the maximum height.

2. Relevant equations

I think a we use Vx = Vox + axt = 0 = 25.5m/s + (-9.8m/s^2)t = -25.5m/s/-9.8m/s^2 = t = 2.6sec

I think on b. we use y = v^2-V^2o/2a = 0-(25.5m/s)^2/2(-9.8m/s^2) = 33.18m

c and d I am stuck
