  )/ time taken for change in velocity acceleration=a= 2.3641 m/s^2 =(22.2222-0)/9.4 mass of the car=m= 1060 Kg Net force required= ma= 2506 N =1060*2.3641 Answer: force that should be exercised on the vehicle in

• A number of simple Q & A's involving acceleration & force

  Constant velocity means that there is no acceleration, ie a = 0 Again use Newtons law to work out the net force Newtons law F(R) = m*a Mass of automobile m = 100 kg Thus net force F(R) = 100 x 0 = 0 N ie no net force on car.

• What is the net force acting on a car travelling downhill with a constant velocity?

  57113 Net force acting on car travelling downhill w/ constant velocity A car is traveling downhill with a constant velocity. Which of the following are true? (a) There is a net force acting on the car in the downhill direction.

• Graphing Force vs. Time

  Hence the force is negative and constant: when a car is pushed away from the origin and released. By definition when the car is pushed, there is a force applied on it in the direction of the push.

• Work, Energy & Power Questions

  Acceleration a = Net force/Mass.

• Forces: Car's magnitude of change in velocity, average acceleration, circular path at constant speed

  Question #6: B The acceleration is centripetal (along a radius) toward the center). Question #7: C Both the centripetal acceleration and the net force are toward the center of the merry-go-round.

• General conceptual physics help

  Newton's second law states that the acceleration (a) is the ratio between the *total* force applied on the body (F) to its mass (m): a=F/m Here the total force applied on the sled is F=50-30=20N.

• 10 Basic Physics Questions: Speed, Force, Acceleration, Velocity.

  Newton's second law states that the acceleration vector a of mass M is proportional to the total net force F exerted on it: (1.4) Since the force is horizontal, the acceleration is horizontal as well/ Therefore, in our case:   3.
