Question

A pickup truck moving at 34 m/sec must come to a stop in a distance of 196 meters to

avoid hitting a boulder that has fallen onto the road. How much time does the driver

have to avoid an accident?

Answer 1

s = d/t (m/s)

s = 34m/s

d = 196m

t = 196/34

Time available to avoid a crash = 5.765 sec
