A truck is accelerated by a constant force of 4.7 kN. Its velocity increases from 38 km/hr to 56 km/hr in a time of 9.3 s. Calculate the mass of the truck in SI units.
Added by Robert C.
Step 1
The conversion factor is \(1 \, \text{km/hr} = \frac{1}{3.6} \, \text{m/s}\). Initial velocity \(v_i = 38 \, \text{km/hr} = \frac{38}{3.6} \, \text{m/s}\). Final velocity \(v_f = 56 \, \text{km/hr} = \frac{56}{3.6} \, \text{m/s}\). Show more…

A truck driving on a level highway is acted on by the following forces: a downward gravitational force of $52 \mathrm{kN}$ (kilonewtons); an upward contact force due to the road of $52 \mathrm{kN} ;$ another contact force due to the road of $7 \mathrm{kN},$ directed east; and a drag force due to air resistance of $5 \mathrm{kN}$, directed west. What is the net force acting on the truck?
