A deer is running east to west on a straight line. It runs (a) at a constant speed of 2.5 m/s for the first 24 sec, (b) at a reduced speed (also constant) of 0.6 m/s for the next 15 sec, (c) sprints at a constant speed of 3.1 m/s for the next 1 minute and 40 seconds. Compute the total distance covered and the average speed in mph.

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

On a two-lane road, car A is travelling with a speed of 72 km/h. Two cars B and C approach car A in opposite directions with a speed of 108 km/h each. At a certain instant, when the distance AB is equal to AC, both being 2 km, B decides to overtake A before C does. What minimum acceleration of car B is required to avoid an accident ?

An object is travelling in 1-dimension (i.e. along the x- axis) with a velocity described by the equation: v(t)=v0+1/6st^3 , where s and v0 are constants. The object’s position, and acceleration at time t = 0 are given by d0, and a0 respectively. In terms of the variables given, what is the average acceleration of the object over the interval from 0 to 2 seconds.
The world land speed record is 763.0 mi/h, set on October 15, 1997, by Andy Green in the jet-engine car Thrust SSC. If we subtract 183 mi/h from this speed, Express the resultant speed in meters per second.
