15 A car of weight \( 1.4 \times 10^{4} \mathrm{~N} \) is moving up an incline at a constant speed of \( 6.2 \mathrm{~ms}^{-1} \).The incline makes an angle of \( 5.0^{\circ} \) to the horizontal. A frictional force of \( 600 \mathrm{~N} \) acts on the car in a direction opposite to the velocity. a i State the net force on the car.

Step 1
a ii) To calculate the force F pushing the car up the incline, we need to consider the gravitational force acting on the car and the frictional force. The gravitational force acting on the car can be divided into two components: one parallel to the incline and Show more…

A block of mass $10 \mathrm{~kg}$ is placed in a car going down an incline of inclination $60^{\circ}$. If the coefficient of friction between the block and car floor is $\frac{1}{\sqrt{3}}$. Find the acceleration $a$ of car down the incline so that the block doesn't slip on the car surface. (a) $a \geq \frac{g}{\sqrt{3}}$ (b) $\alpha \geq \frac{2 g}{\sqrt{3}}$ (c) $a<\frac{g}{\sqrt{3}}$ or $a>\frac{2 g}{\sqrt{3}}$ (d) $\frac{g}{\sqrt{3}} \leq a \leq \frac{2 g}{\sqrt{3}}$

Section B
A car accelerates uniformly from rest to 20.0 m/s in 5.6 s along a level stretch of road. Ignoring friction, determine the average power required to accelerate the car if $(a)$ the weight of the car is $9.0 \times 10^{3} N$ and $(b)$ the weight of the car is $1.4 \times 10^{4} N .$
