Adiver jumps up off a pier at an angle of 25° with an initial velocity of 3.2 m/s. how far from the pier will the diver hit the water? (assume the level of the water us the same as the pier)

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);

where u is the initial velocity, is the angle of projection and g is acceleration due to gravity which is taken as .

Given;

u = 3.2m/s and .

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

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
