Problema Solution
if a ball rolls down an inclined plane, it's velocity v(t) (in cm/sec) at time t (in seconds) is given by v(t)=v(subzero)+at for initial velocity v(subzero) and acceleration a (in cm/sec^2). if v(2)= 16 and v(5)=25 find v and a
Answer provided by our tutors
v(2)= 16 and v(5)=25
v + 2a = 16
v + 5a = 25
by solving the above system of equations we find:
a = 3 cm/sec^2
v = 10 cm/sec
