Q1. A car is travelling at 60.0 km/h on a flat highway.
If the coefficient of friction between road and tires on a rainy day is 0.150, what is the minimum distance in that car will stop?
What is the stopping distance when the surface is dry and the coefficient of friction is 0.620?
Q2. A snowmobile is originally at the point with position vector 29 m at 95.0° counter clockwise from x axis, moving with velocity 4.50 m/s at 40.0°. It moves with constant acceleration 1.90 m/s2 at 200°. After 5s have elapsed, find out (a) its velocity and (b) its position vector.
A 61 kg speed skater with the velocity of 16 m/s comes into a curve of 18 m radius. How much friction should be exerted between skates and ice to negotiate the curve.
