Question
1) You and a friend have just loaded a 200 kg crate filled with priceless art objects into the back of a 2000 kg truck. As you press down on the accelerator, force Fsurface on truck propels the truck forward. To keep things simple, call this FT. What is the maximum magnitude FT can have without the crate sliding? The static and kinetic coefficients of friction between the crate and the bed of the truck are 0.80 and 0.30. Rolling friction is negligible. Draw free-body diagrams for the crate and the truck separately.Explanation / Answer
The crate will have a forward force due to friction (static) and a backward psuedo force due to trucks acceleration
now, for crate to remain stable
Ft*(200/2000) = .8*200*9.81
Ft = 15696N
