Q1. A highway curve with a radius of 555 m is banked properly for the car travelling 150 km/h. If a 1650 kg Porshe 928 S rounds the curve at 220 km/h, how much sideways force must the tires exert against the road if the car does not skid?

Q2. A 37.0 g piece of cadmium is at 10°C. If 365 cal of energy is added to the cadmium, what is its final temperature?

#### Explain how you would use the force table to add the vectors

Explain how you would use the force table to add the vectors 1.50 N at 0 degrees and 1.00 N at 180 degrees. Would there be any problem or difficulty in doing this on the for

#### Slides without friction to the bottom of the ramp

The figure below shows shows a 1.75-kg block at rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continue

#### Determine the magnitude of the magnetic force

Each of the lettered dots a-d shown in the figure represents a +1.0x10-5-C charged particle moving at speed 2.0x107m/s. A uniform 0.50-T magnetic field points in the positive

#### What is the impulse given to the driver

A 50kg driver sits stopped at a traffic light. Another car rear-ends her and causes her to accelerate at 16m/s^2. It all occurs in 0.25s. What is the impulse given to the dr

#### Find the force acting on each attachment

A 2.18-m-long diving board of mass 13.2kg is 3.00m above the water. It has two attahcments holding it in place. Assuming that the board has a uniform density, find the force a

#### What is the length of the rotating string

A string trimmer is a tool for cutting grass and weeds; it utilizes a length of nylon "string" that rotates about an axis perpendicular to one end of the string. What is the

#### How long does it take to travel the same distance

A space probe has two engines. Each generates the same amount of force when fired, and the directions of these forces can be independently adjusted. How long does it take to

#### Estimate the speed of the arrow as it leaves the bow

A 92 gram arrow is fired from a bow whose string exerts an average force of 100 N on the arrow over a distance of 75 cm. Determine the speed of the arrow as it leaves the bo
