(a) Explanation Given: The braking distance can be calculated using a formula d = v 2 2 μ g . The braking distance of an accident is 49 m. on a dry pavement. Calculation: The given formula to obtain the braking distance is d = v 2 2 μ g , where v is velocity, µ is the coefficient of friction and g is the acceleration due to gravity on Earth which is ≈ 9.8 m / s 2 . Here the braking distance is 49 meters, coefficient of friction is 0.80. So, substitute d = 49 , μ = 0.80 and g = 9.8 in the above formula as follows. d = v 2 2 μ g 49 = v 2 2 ( 0.80 ) ( 9.8 ) 49 = v 2 15.68 49 ( 15.68 ) = v 2 15 (b) To determine To find: The velocity of the vehicle in kilometers per hour.

The trees take about 25 years to get established, and from that point on, for the next 25 years, they give a fairly good yield. But after 50 years, age and disease are taking their toll, and the annual yield is falling off. 40 35 30 。 ៣៩ ថា8 8 8 8 6 25 20 15 10 y 5 0 0 5 10 15 20 25 30 35 40 45 50 55 60 The orchard problem is this: when should the orchard be cut down and re- planted, thus starting the cycle again? What you want to do is to maximize your average harvest per year over a full cycle. Of course there are costs to cutting the orchard down and replanting, but it turns out that we can ignore these. The first cost is the time it takes to cut the trees down and replant but we assume that this can effectively be done in a week, and the loss of time is negligible. Secondly there is the cost of the labour to cut…
