Homework Help: PHYSİCS

Posted by MARİA on Friday, February 24, 2012 at 1:16pm.

At the end of the spring term, a high school physics class celebrates by shooting a bundle of exam papers into the town landfill with a homemade catapult. They aim for a point that is 31.1 m away and at the same height from which the catapult releases the bundle. The initial horizontal velocity component is 5.87 m/s.

a) What is the initial velocity component in the vertical direction?

b) What is the launch angle? (in degrees)

The range for a projectile is

R = v^2/g sin2θ

Now, 5.87/v = cosθ
v = 5.87 secθ

31.1 = 5.87²/9.8 sec²θ * 2sinθcosθ

4.4227 = tanθ
θ = 77.26°
v = 26.62
