You stand 17.5 m from a wall holding a softball. You throw the softball at the wall at an angle of 30.5 ∘ from the ground with a
Levart [38]

Answer:

5.39 m

Explanation:

From kinematics

s=u_x t where t is time, s is distance and u_x is initial speed in x direction

u_x= 20.5cos 30.5=17.6634 m/s

u_y= 20.5 sin 30.5=10.40454 m/s

Now 17.5=17.6634 t

t=\frac {17.5}{17.6634} =0.99 s

Using the equation of kinematics

h=u_y t- 0.5gt^{2}

h=10.40454\times 0.99^{2}-0.5\times 9.81\times 0.99^{2}

h=5.39 m

What Is the definition of the term gravitational potential energy​
OLga [1]

Answer:

Here are all the possible meanings and translations of the word gravitational energy. Gravitational energy is the potential energy associated with the gravitational field. This phrase is found frequently in scientific writings about quasars and other active galaxies. Quasars generate and emit their energy from a very small region.

A 51.0 kg cheetah accelerates from rest to its top speed of 31.7 m/s. HINT (a) How much net work (in J) is required for the chee
andrey2020 [161]

(a) 2.56\cdot 10^4 J

The work-energy theorem states that the work done on the cheetah is equal to its change in kinetic energy:

W= \Delta K = \frac{1}{2}mv^2 - \frac{1}{2}mu^2

where

m = 51.0 kg is the mass of the cheetah

u = 0 is the initial speed of the cheetah (zero because it starts from rest)

u = 31.7 m/s is the final speed

Substituting, we find

W=\frac{1}{2}(51.0 kg)(31.7 m/s)^2 - \frac{1}{2}(51.0 kg)(0)^2=2.56\cdot 10^4 J

(b) 6.1 cal

The conversion between calories and Joules is

1 cal = 4186 J

Here the energy the cheetah needs is

E=2.56\cdot 10^4 J

Therefore we can set up a simple proportion

1 cal : 4186 J = x : 2.56\cdot 10^4 J

to find the equivalent energy in calories:

x=\frac{(1 cal)(2.56\cdot 10^4 J)}{4186 J}=6.1 cal
