A cyclist travels down an inclined road without pedalling.The angle that road makes with the horizontal is 6.8 degrees.
Question1)The cycle is serviced in order to reduce friction and then the journey down the slope is repeated.State and explain what change,if any,will occur in the maximum velocity of the cycle down the slope.
Question2) Having descended the slope,the cyclist travels along a horizontal straight section of road at a speed of 7.0 m/s.When the brakes are applied,the cyclist takes 3.5 s to come to rest.
2a)Calculate average force opposing motion during the time the brakes are applied,assuming the cyclist is not pedalling.
