Waec Model Questions Vol1 2020 Physics Question 3 diagram

A child runs in a straight line and a motion diagram of the motion is drawn. The diagram shows the positions of the child at successive equal time intervals of 0.5 s. The distances between successive positions are 2 m, 3 m, 4 m and 5 m respectively.

Question Parts

( a )

Determine the magnitude of the child's constant acceleration and the initial speed at the start of the first interval.

( b )

Calculate the speed of the child after 2.0 s from the start.

( c )

Find the total distance travelled by the child in the first 2.0 s.

( d )

Sketch a velocity‑time graph for the motion from t = 0 to t = 2.0 s. State the gradient of the graph and explain what the area under the graph represents.
