Draw a free-body diagram. Straight down should be the force of gravity, then perpendicular to the slope should be the normal force. Set your coordinate axes in the direction of acceleration. So for the force sums, you'll get in one direction (call it x, the direction of acceleration):
Fx(total) = mgsin(theta) = ma
where theta is the angle. The mass cancels out, so a = gsin(theta)How do I find the acceleration of an object, when only given the angle of the slope the object is on.?
u time the speed of the object. stop it wen it the wheels reaches the end of the slope. the fomula of acceleration is acceleration= final velocity- initial velocity and the whole thing divided by the time. so in this case, the time= time it takes for the object to go down the slope.How do I find the acceleration of an object, when only given the angle of the slope the object is on.?
acceleration should only be gravity, unless other external forces are acting on it? gravity=9.81m/s^2
