Agent Bond is standing on a bridge, 12 m above the road below, and his
Pursuers are getting too close for comfort. He spots a flatbed truck approaching at 25 m/s
Which he measures by knowing that the telephone poles the truck is passing are 25 m
Apart in this country. The bed of the truck is 1.5 m above the road, and Bond quickly
Calculates how many poles away the truck should be when he jumps down from the
Bridge onto the truck to make his getaway. How many poles is it?

A 28.0-kg block is connected to an empty 1.35-kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.450 and the coefficient of kinetic friction between the table and the block is 0.320. Sand is gradually added to the bucket until the system just begins to move. (a)Calculate the mass of sand added to the bucket. (b)Calculate the acceleration of the system.
