Question
A van moves at $60 \mathrm{~km} / \mathrm{h}$ and completely stops with constant deceleration in $5 \mathrm{~s}$. The mass of the van and driver is $2075 \mathrm{~kg}$, find the necessary force.
Step 1
We can do this by multiplying the speed in km/h by 1000 to convert it to meters and then dividing by 3600 to convert it to seconds. So, the speed in m/s is: \[ v = 60 \times \frac{1000}{3600} = 16.67 \, \text{m/s} \] Show more…

A car is driven at $60 \mathrm{km} / \mathrm{h}$ and is brought to a full stop with constant deceleration in 5 s. If the total car and driver mass is $1075 \mathrm{kg}$, find the necessary force.
A minivan of mass $1560 \mathrm{kg}$ starts at rest and then accelerates at $2.0 \mathrm{m} / \mathrm{s}^{2}$. (a) What is the object exerting the force on the minivan that causes it to accelerate? What type of force is it? (b) Air resistance and other opposing resistive forces are 300 N. Determine the magnitude of the force that causes the minivan to accelerate in the forward direction.
