Area near a sea having flat land and low relief
m= 60g = 60/1000 Kg = 0.06 Kg
v = 2cm3 = 2 * (0.01^3) m3 = 2 *10^-6 m3
Density= m/v = 6 * 10^-2 / 2 *10^-6 = 3 *10^4 Kg/m3
A field is the description of a spatial region, the force exerted on objects by a field is a field force.
gravitational force field: surrounds every material object, although only objects planet-sized or larger exert significant gravity.
electric force field: surrounds and affect electrical charges
magnetic force field: surround magnets and materials with electricity flowing through them. magnetic fields affect susceptible materials such as iron or other magnets.

Given that,
Height =1.5 m
Angle = 45°
We need to find the greater speed of the ball
Using conservation of energy
Here, initial velocity and final potential energy is zero.
Put the value into the formula
Hence, the greater speed of the ball is 5.42 m/s.
