Intergated chemistry/physics
If a bowling ball is rolling at a speed of 1.5 meters/second and has a momentum of 10.0 kg m/s, what is the mass of the ball in kilograms?

Intergated chemistry/physics
Which has more momentum: a 45 gram golf ball travelling at 180 miles per hour or a 430 gram soccer ball travelling at 20 miles per hour?

Intergated chemistry/physics
What is the momentum of a 100 kilogram football player moving with a speed of 3.5 meters/second. The units should be written as kg m/s.

Intergated chemistry/physics
If you were in a car traveling 50 miles/hours, how many miles could you travel if you continued for 15 hours without stopping?

Intergated chemistry/physics
If you were in a car travelling at 50 miles/hour, how many hours would it take to get to Miami, FL from Evansville, IN? Assume that there is no stopping on the way. Miami is 1,060 miles from Evansville.

Intergated chemistry/physics
If the elevator were falling on the moon 9800 meters/second^2, what would the force be? (hint: you will need to look up the acceleration due to gravity on the moon.)

Intergated chemistry/physics
The Lamborghini Diablo sports car can accelerate from 0 kilometers/hour to 99.2 kilometers/hour in 4.0 seconds. What is the acceleration of this car in kilometers/hour^2. (hint: you must convert 4.0 seconds before putting it into the equation.)

Intergated chemistry/physics
A car is accelerated at a rate of 2.5 meters/second^2. If the starting speed is 5.0 meters/second, how many seconds will it take the car to reach a final speed of 27.0 meters/second?

Intergated chemistry/physics
A parachute on a dragster racing-car opens and changes the speed of a car from 85 meters/second to 45 meters/second. Of this car is decelerating (slowing down) at a rate of -8.9 meters/ second, how many seconds will this take?

Physics
A boat, having an initial velocity of 6.6m/s east undergoes an average acceleration of 2.2 m/s squared south for 2.5 s. Determine final velocity after the time interval (magnitute and direction)
