Aroller coaster car moving at a velocity of 30 meters/second has a momentum of 2.5 × 104 kilogram meters/second. what is its mass? whats the answer for this question

830 kg

Explanation:

Momentum = mass × velocity

2.5×10⁴ kg m/s = m (30 m/s)

m = 833.3 kg

Rounded to two significant figures, the mass is 830 kg.

The mass of roller coaster car is

Explanation:

We know momentum of any body is product of its mass and its velocity.

Using the above relation we can form an equation,

P=mv

where

P =momentum

m=mass

v=velocity

Re arranging the equation, we have

m = P / v

Now substituting the values,

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
