Question

(1)A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 4.5 m/s. The car is a distance d away. The bear is 27 m behind the tourist and running at 6.0 m/s. The tourist reaches the car safely. What is the maximum possible value for d?

(2)For a standard production car, the highest road-tested acceleration ever reported occured in 1993, when a Ford RS200 Evolution went from zero to 26.8 m/s (60 mi/h) in 3.275 s. Find the magnitude of the car's acceleration.

m/s2
Repeat your calculation for another car which goes from zero to 60 mi/h in 4.865 s.
m/s2

Explanation / Answer

let time taken be t

for this time is same for both

(27+d)/6 = d/4.5 = t

6d = 4.5d+121.5

d = 81 m

2) (26.8-0)/3.275 = 8.183 m/s^2

26.8/4.865 = 5.509m/s^2
