Resumen del Recurso

Pregunta 1

Pregunta
A ball is dropped from a height of 1.3 m. The graph shows how the height above the ground varies with time for several bounces. At 2.6 s the magnitude of the displacement from the starting position is:
Respuesta
  • A 0.20 m
  • B 0.60 m
  • c 0.70 m
  • D 1.30 m

Pregunta 2

Pregunta
How can the velocity of the ball at time t = 2.5 s be determined from the graph?
Respuesta
  • A Calculate the area between the graph and the time axis up to t = 2.5 s.
  • B Divide the displacement at t = 2.5 s by 2.5 s.
  • C Divide the height at t = 2.5 s by 2.5 s.
  • D Draw a tangent to the graph at t = 2.5 s and calculate its gradient.

Pregunta 3

Pregunta
A ball is thrown from position L and caught at position N. L and N are the same height above the ground. If vectors directed upwards are taken as positive, and air resistance is neglected, then the acceleration of the ball at L is -g and its speed is v. Select the row of the table that correctly gives the acceleration and the speed of the ball as it reaches N.
Respuesta
  • A
  • B
  • C
  • D

Pregunta 4

Pregunta
A box is dropped from a plane flying at a constant velocity and height. Assuming that air resistance is negligible, as the box falls to the ground its horizontal position will -
Respuesta
  • A remain unchanged
  • B lag behind the plane
  • C move ahead of the plane
  • D remain directly under the plane.

Pregunta 5

Pregunta
A ball launcher fires a ball horizontally of a lab bench. The paths of the ball after two launches are shown in the diagram. Which of the following quantities are different for the two launches?
Respuesta
  • A gravitational acceleration
  • B time of flight
  • C launch angle
  • D initial velocity
