Answer:

0.80m

Explanation:

The problem requires that we calculate the range covered by the diver, here the diver is assumed to be a particle undergoing projectile motion.

The range, R is given by equation (1);

R=\frac{u^2sin2\theta}{g}......................(1)

where u is the initial velocity, \theta is the angle of projection and g is acceleration due to gravity which is taken as 9.8m/s^2.

Given;

u = 3.2m/s and \theta=25^o.

Substituting these into equation (1), we obtain the following;

R=\frac{3.2^2sin2(25)}{9.8}\\R=\frac{10.24*sin50}{9.8}\\R=\frac{10.24*0.7660}{9.8}\\R=0.80m
