How to solve problems about a block being projected up a frictionless incline?
A retard is projected up an 31.7 grade slip with a since primary velocity. How do we get how tall up a slip a retard reaches, how prolonged it takes to get there, as well as a speed when it gets behind to a bottom?
Think about how you would solve it if the angle of the incline was 90 degrees – straight up! [sin(incline angle) = 1]
The thing would be just a straight kinematics problem with a deceleration of ‘g’.
If the incline was zero, same again, but the deceleration would be zero.
[sin(incline angle) = 0]
At all intervening angles the deceleration will be a fraction of ‘g’ which is the component of ‘g’ down the slope = g * sin(angle of incline)
