Physics

Brut [27]3 years ago

Answer:

v = 5.95 m/s

Explanation:

Given,

The mass of the baseball, m = 0.150 Kg

The kinetic energy (K.E) of the baseball, E = 118 J

The kinetic energy of a body is directly proportional to the square of its velocity. The formula for kinetic energy is given by

                                      E = 1/2 mv²     joules

Solving for v

                                  v² = 2mE

                                  v = \sqrt{2mE}   m/s

Substituting the given values in the above equation,

                                 v = \sqrt{2X0.15X118}      

                                         v = 5.95 m/s

Hence, the velocity of the baseball is,  v = 5.95 m/s

polet [3.4K]

Answer: The horizontal location of the plane will BE OVER THE BOMB

Explanation:

As soon as the bomb was dropped, the bomb will fall under gravity (free fall) and the location of the plane continues to increase horizontally till the bomb reaches the ground which is a falling distance to be travelled by the bomb at 9.8m/s²

A proton in a high-energy accelerator is given a kinetic energy of 50.0 GeV. Determine (a) the momentum and (b) the speed of the
koban [17]

(a) The momentum of the proton is determined as 5.17 x 10⁻¹⁸ kgm/s.

(b) The speed of the proton is determined as  3.1 x 10⁹ m/s.

<h3>Momentum of the proton</h3>

The momentum of the proton is calculated as follows;

K.E = ¹/₂mv²

where;

  • m is mass of proton = 1.67 x 10⁻²⁷ kg
  • v is speed of the proton = ?
<h3>Speed of the proton</h3>

v² = 2K.E/m

v² = (2 x 50 x 10⁹ x 1.602 x 10⁻¹⁹ J)/(1.67 x 10⁻²⁷)

v² = 9.6 x 10¹⁸

v = 3.1 x 10⁹ m/s

<h3>Momentum of the proton</h3>

P = mv = (1.67 x10⁻²⁷ x 3.1 x 10⁹) = 5.17 x 10⁻¹⁸ kgm/s
