In the absence of air resistance, at what other angle will a thrown ball go the same distance as one thrown at an angle of 75 de

snow_tiger [21]

As we know that range of the projectile motion is given by

$R = \frac{v^2 sin(2\theta)}{g}$

here we know that range will be same for two different angles

so here we can say the two angle must be complementary angles

so the two angles must be

$\theta, 90 - \theta$

so it is given that one of the projection angle is 75 degree

so other angle for same range must be 90 - 75 = 15 degree

so other projection angle must be 15 degree

An electron starts from rest in a vacuum, in a region of strong electric field. The electron moves through a potential differenc

Semenov [28]

Answer:

The kinetic energy is $KE = 5.67*10^{-18} \ J$

Explanation:

From the question we are told that

The potential difference is $\Delta V = 36 \ volts$

The potential energy of the end is mathematically represented as

$PEs = - q * \Delta V$

q is the charge on an electron with a constant value of $q = 1.60 *10^{-19} \ C$

substituting values

$PE = - 1.60*10^{-19} * 36$

$PE = - 5.67*10^{- 18} \ J$

Now from the law of energy conservation

The $PE_e = KEe$

Where $KE _e$ is the potential energy at the end

$KE = 5.67*10^{-18} \ J$

The negative sign is not includes because kinetic energy can not be negative
