Homework Statement
A tire with radius 0.50m rolls in a straight line without slipping. The center moves with constant speed 6.7 m/s. A small pebble stuck in the tread of the tire is in contact with the road at time t=0. The total time is 14.1s. The horizontal position of the pebble at time t = 94.26m.
Calculate the vertical position y of the pebble at time t.
Calculate the horizontal velocity of the pebble at time t.
Calculate the vertical velocity of the pebble at time t.
Homework Equations
the integral of velocity from t=0s to t=14.1s
y=rsin(theta)
The Attempt at a Solution
I thought that since x=94.26m then the equation x=rcos(theta) could tell me what theta was.
