1. A body with initial velocity 8.0 m/s moves along a straight line with constant acceleration and travels 640 m in 40 s. For the 40 s interval, find (a) the average velocity, (b) the final velocity, and (c) the acceleration.

2. A mass of 10 kg is hanging from a spring scale that is in turn hanging from a hook attached to the ceiling. The scale indicates a reading of 98 N for the force. Then two people hold the spring scale horizontally and pull on opposite ends until the scale again reads 98 N. With what force must each person pull to attain this result?

3. A train running along a straight track at 30 m/s is slowed uniformly to a stop in 44 s. Find the acceleration and the stopping distance.

  • Graphing Force vs. Time

    When the velocity increases the acceleration is positive and so is the force. When the car slows down, the acceleration turns negative (points against the direction of motion) and the force is negative.

  • Speed, Velocity, Acceleration

    Importantly, it also implies that force and acceleration must have the same vector: if the net force is to pull something backwards, the acceleration is also backwards, and vice versa.

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

    Change of velocity is examined over a known time to derive the acceleration of that body, Newtons second Law is used to detemine the net acceleration of a body of known mass when two opposing unequal forces are applied to that body and the net force acting

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

    The car's magnitude of change in velocity, and average acceleration is discussed.

  • Force and Newton's 2nd law

    Initial velocity= 0 m/s Final velocity= 2.3 m/s time required to reach the final velocity= 10.3 s acceleration =a= rate of change of velocity = (final velocity - initial velocity)/ time taken for change in velocity acceleration

  • The Round Trip

    E) The normal (vertical) force on bicycle and ride is a constant because the vertical acceleration is zero. F) The magnitude of the bicycle + riders weight is constant; same reason as E).

  • Force and acceleration

    Thus a) The acceleration of a body is the rate to change of velocity and thus the average acceleration is given by the ratio of change in velocity to the time interval.
