Question 2 NECO • 2018 • PHYSICS • essay

A projectile is launched from ground level. The motion diagram of its flight is shown, with positions marked at each 1‑second interval. The horizontal distance between successive marks is uniform. The diagram indicates the vertical heights of the projectile at the marked instants as follows: at t = 0 s the projectile is at the launch point (height 0 m); at t = 1 s the height is 15 m; at t = 2 s the height is 20 m; at t = 3 s the height is 15 m; at t = 4 s the projectile returns to the ground (height 0 m). The total horizontal range measured from the diagram is 80 m. Using the information from the motion diagram, answer the following:

( a )

Determine the acceleration due to gravity (g) acting on the projectile.

( b )

Calculate the initial vertical component of the velocity (u_y).

( c )

Find the magnitude of the initial velocity and the angle of projection with the horizontal.

( d )

State the maximum height reached by the projectile and the time at which it occurs.
