Answer:
68.5N
Explanation:
When the dolphin decelerates from 12m/s to 7.5 m/s within 2.3s. Then its acceleration is:
The dolphin has a mass of 35kg, according to the Newton's 2nd law, the force exerted on it must be:
Contact area is not a factor of the amount of friction force acting between two bodies in contact, preventing rolling or sliding
Reasons:
- Friction force is the product of the normal reaction and the coefficient of friction.
- The coefficient of friction is higher in softer tires than hard tires which are required to be wider to reduce the pressure that can cause deformation withstood by hard tires.
- The wide tires in drag racing cars can be thought of being made from the soft compound tire material having a higher coefficient of friction that increases the friction force.
Other advantages of wide tires are;
- Shorter stopping distance
