The froghopper, a tiny insect, is a remarkable jumper. suppose you raised a colony of the little critters on titan, a moon of sa

turn, where the acceleration due to gravity is only 1.35 m/s2, compared to the earth value of g = 9.81 m/s2. if on earth a froghopper\'s maximum height is h and maximum horizontal range is r, what would its maximum height and range be on titan in terms of h and r? assume the froghopper\'s takeoff velocity is the same on titan as on earth.

In projectile motion we know that range of projectile is given as

R = \frac{v^2 sin2\theta}{g}

also the maximum height is given as

H = \frac{v^2sin^2\theta}{2g}

so here we can see that maximum height and range on earth will inversely depends on gravity

now if we compare this height and range on earth and moon

\frac{R_E}{R_M} = \frac{g_m}{g_e}

\frac{R}{R_M} = \frac{1.35}{9.8}

R_M = \frac{R* 9.8}{1.35} = 7.26 R

similarly for height we have

\frac{H_E}{H_M} = \frac{g_m}{g_e}

\frac{H}{H_M} = \frac{1.35}{9.8}

H_M = \frac{H* 9.8}{1.35} = 7.26 H

so both will increase by factor of 7.26

The height to which the frog-hopper jumps on the surface of titan will be \boxed{7.26h} and the range of the frog-hopper will be \boxed{7.26R}.

Explanation:

The motion of the projectile on the surface of the planet occurs in two dimension. The vertical motion of the frog-hopper will be under the action of the gravity whereas the horizontal motion of the frog-hopper will be the motion under constant speed.

Write the expression for the maximum height attained by the frog-hopper:

h=\dfrac{v_{y}^2}{2g}                                               ...... (1)

Here, h is the maximum height attained by the frog-hopper, v_y is the velocity in vertical direction.

Consider that the height attained by the frog-hopper on the surface of titan is h_{T} and h_{E} on the surface of Earth.

Compare the maximum heights attained by the frog-hopper on Earth and titan:

\dfrac{h_{E}}{h_{T}}=\dfrac{g_T}{g_E}

Substitute the value of the acceleration due to gravity on each surfaces.

\begin{aligned}\dfrac{h}{h_T}&=\dfrac{1.35\text{ m/s}^2}{9.81\text{ m/s}^2}\\h_T&=7.26h\end{aligned}

Write the expression for the range of jump of the frog-hopper:

R=\dfrac{v^2sin2\theta}{g}                                                    ...... (2)

Compare the range of the frog-hopper on the surface of Earth and titan:

\dfrac{R_{E}}{R_{T}}=\dfrac{g_T}{g_E}

Substitute the value of the acceleration due to gravity on each surfaces.

\begin{aligned}\dfrac{R}{R_T}&=\dfrac{1.35\text{ m/s}^2}{9.81\text{ m/s}^2}\\R_T&=7.26R\end{aligned}

Thus, the height to which the frog-hopper jumps on the surface of titan will be \boxed{7.26h} and the range of the frog-hopper will be \boxed{7.26R}.

A shot is fired at an angle of 60 degree horizontal with Kinetic energy E. If air resistance is ignored, the K.E at the top of t
Lapatulllka [165]
I'm not sure what "60 degree horizontal" means.

I'm going to assume that it means a direction aimed 60 degrees
above the horizon and 30 degrees below the zenith. 

Now, I'll answer the question that I have invented.

When the shot is fired with speed of 'S' in that direction,
the horizontal component of its velocity is    S cos(60)  =  0.5 S ,
and the vertical component is   S sin(60) = S√3/2  =  0.866 S .  (rounded)

-- 0.75 of its kinetic energy is due to its vertical velocity.
That much of its KE gets used up by climbing against gravity.

-- 0.25 of its kinetic energy is due to its horizontal velocity.
That doesn't change. 

-- So at the top of its trajectory, its KE is 0.25 of what it had originally. 

That's  E/4 .
