A compact car, mass 664 kg, is moving at 19 km/h toward the east. What is the car's momentum in kg x m/s?
Natasha2012 [34]

Answer:

3504.4 kgm/s

Explanation:

First, convert km/hr to m/s:

19 km/hr x 1000m/1km x 1/60min x 1/60s = 5.28 m/s

p = mv

p = (664 kg)(5.28 m/s) = 3504.4 kgm/s

The displacement of a moving object in given interval of time is zero . Would the distance travelled by the object also be zero.
kirill [66]





Hi Pupil Here's Your answer ::




➡➡➡➡➡➡➡➡➡➡➡➡➡



No, on a circle in going from one point around circular path the displacement is zero but the distance covered is equal to the circumference of the circle.

i.e.


2\pi r

If there are no windows, then the illumination in the room depends
only on the room and what's in it, not on anything outside. 
The time of day has no effect.  The other things all do.

If raindrops are falling vertically at 8.30 m/s, what angle from the vertical do they make for a person jogging at 2.07 m/s?
dmitriy555 [2]

Answer:

∆ = 14°

Explanation:

Let the angle be ∆

Opposite = 2.07 m/s

Adjacent = 8.3 m/s

Tan ∆ = opposite / adjacent

Tan ∆ = 2.07 / 8.3

Tan ∆ = 0.2494

∆ = ArcTan (0.2494)

∆ = 14°

The angle from vertical the raindrops make for a person jogging is 14°

If there is no friction in a rollercoaster is the speed the same throughout?
andrey2020 [161]
If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
