Answer:
Divide the change in velocity by the time interval
Explanation:
Acceleration is defined as the rate of change of velocity.
mathematically it is the change in velocity divided by the time taken for that change.
i.e Divide the change in velocity by the time interval.
u = 0.077
Explanation:
Work done by friction is
Wf = ∆KE + ∆PE
-umgx = ∆KE,. ∆PE =0 (level ice surface)
-umgx = KEf - KEi = -(1/2)mv^2
Solving for u,
u = v^2/2gx
= (12 m/s)^2/2(9.8 m/s^2)(95 m)
= 0.077
