Question 29

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A particle P P\,P is projected from a point on horizontal ground with velocity k(3i+4j)k(3\mathbf{i} + 4\mathbf{j})k(3i+4j) m s−1^{-1}−1, where k k\,k is a positive constant, i\mathbf{i}i is horizontal and j\mathbf{j}j is vertically upwards. Air resistance is modelled as negligible.

The greatest height reached by P P\,P is 24 m above the ground.

a.

Find the value of kkk.

[3]
b.

Find the horizontal distance travelled by P P\,P before it returns to the ground.
