Question

A car is going at a speed of 6 m/s when it encounters a 15 m slope of angle . The friction coefficient between the road and tyre is 0.5. The driver applies the brakes. The minimum speed of car with which it can reach the bottom is $open parentheses straight g equals 10 straight m divided by straight s squared close parentheses$

4 m/s
3 m/s
7.49 m/s
8.45 m/s

The correct answers are: 7.49 m/s, 8.45 m/s

A block of mass m = 2 kg is resting on a rough inclined plane of inclination 30⁰as shown in figure. The coefficient of friction between the block and the plane is $µ$ = 0.5. What minimum force F should be applied perpendicular to the plane on the block, so that block does not slip on the plane (g=10m/ $s to the power of 2 end exponent$ )

If $a with minus on top equals i with minus on top plus j with minus on top plus k with minus on top text and end text b with minus on top equals stack i with minus on top minus j with minus on top with blank on top$ then the vectors $Error converting from MathML to accessible text.$ and $Error converting from MathML to accessible text.$

We can check for parallelepiped. We can take the scalar product of the given vectors. If we do that, we will find the volume to be 6 units. It doesn't match any option.
