A projectile is fired at an angle α to the horizontal at a speed u, as shown. What will be the vertical and horizontal components of its velocity after a time t ? Assume that air resistance is negligible. The acceleration of free fall is g
1 )
vertical component: u sin α / horizontal component: u cos α
2 )
vertical component: u sin α – gt / horizontal component: u cos α – gt
vertical component: u sin α – gt / horizontal component: u cos α
4 )
vertical component: u cos α / horizontal component: u sin α – gt
