A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it is rotating at 4.00 rev/s; 70.0 revolutions later, its angular speed is 22.0 rev/s. Calculate (a) the angular acceleration (rev/s2), (b) the time required to complete the 70.0 revolutions, (c) the time required to reach the 4.00 rev/s angular speed, and (d) the number of revolutions from rest until the time the disk reaches the 4.00 rev/s angular speed.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
