Can anyone help with these 2?
I can't seem to figure out how to get the answer of 2.8m for this ...
IF you throw a ball at an initial velocity of 26 m/s at an angle of 20 above the horizontal, how high above the projection point is the ball after 2.8 s?
and also
You drag a crat weighing 311 N across a floor by pulling on a rope attatched to the crate. You exert a force of 450N on the rope inclined at 38 degrees, and the floor exerts a horizontal force of 125 N, the acceleration is ...
(do you add the forces, for total force? what do you do with the 38 degrees ?)
