A force of $1600\,\text{N}$ causes a car of mass $800\,\text{kg}$ to speed up from rest. What are the car’s acceleration and its velocity after $4.0\,\text{s}$?
- Aacceleration $0.50\,\text{m s}^{-2}$, velocity $0.13\,\text{m s}^{-1}$
- Bacceleration $0.50\,\text{m s}^{-2}$, velocity $0.50\,\text{m s}^{-1}$
- Cacceleration $2.0\,\text{m s}^{-2}$, velocity $2.0\,\text{m s}^{-1}$
- Dacceleration $2.0\,\text{m s}^{-2}$, velocity $8.0\,\text{m s}^{-1}$
