Answer:
9.6 m/s
Explanation:
Angle of projection, θ = 28°
Horizontal distance, R = 7.8 m
Let the velocity of projection is given by u.
The formula used to find the velocity of projection is given by



u = 9.6 m/s
Thus, the velocity of projection is 9.6 m/s.

Explanation:
Work SI unit = joule = N*m= [kg]*[m/s^2] *[m] = kg * m^2/s^2
Work cgs unit = erg = [g][cm/s^2][cm] = g*cm^2 / s^2
Then 1 kg * m^2 / s^2 * [1000 g/kg] * [100cm/m]^2 = 10,000,000 g*cm^2/s^2
The relation is 1 joule = 10,000,000 erg or 1 erg = 10^-7 joule
His acceleration is
<em>(-0.05) · (his speed at the bottom of the hill) </em>m/s²
As we presume that the fluid density is greater than the gas density based on common sense, the volume of the balloon decreases. The mass per unit volume is known as fluid density.
Greek letter stands in for and (rho). Mass per length squared, or M/L3, is the unit of measurement for density. Specific Weight vs. Weight Density: A fluid density, also known as specific density, is determined by dividing the fluid's weight by its volume. Weight per volume of a fluid is also referred to as weight density.
A mathematical term called "volume" describes how much three-dimensional space is occupied by an item or a closed surface. The measurement of volume is done in cubic units, like m3, cm3, in3, etc.
