What is the kinetic energy of a 2 kg snowball thrown through the air at 5 m/s?

Kinetic energy of the ball is 25 joules.

Explanation:

Mass of the snowball, m = 2 kg

Speed of the ball, v = 5 m/s

Let E is the kinetic energy of the snowball. The energy possessed due to the motion of an object is called its kinetic energy. Mathematically, it is given by :

E = 25 joules

So, the kinetic energy of ball is 25 joules. Hence, this is the required solution.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
