Ok, i just need to verify what this question means:
A baseball pitcher throws a ball straight up into the air at a speed of 20 m/s as a protest against the umpire's calls. In the process, he moves his hand through a distance of 1.5 m. If the ball has a mass of 0.15 kg, find the force he...
Try plotting the points on a graph paper, it will help you vizualize
Now here are some hints:
Square as 4 congruent sides
Square has at least 1 right angle
look up the distance formula in ur textbook and how to find slope, and how slopes are in right angles
"Respect" Newton question
Ok here's the question:
A boy drags a 100-N sled up a 20 degree slope at constant velocity. If the coefficient of friction between sled and hill is 0.2, what force must he exert at an angle of 35 degree with respect to the hill?
Ok, I've done the FBD and...
