Answer:
In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.

Answer:
Speed of the car around the circular path will be 12 m/sec
Explanation:
We have given mass of the car m = 1500 kg
Radius of the curve r = 45 m
Centripetal acceleration of the car
We have to find the speed of the car
We know that centripetal acceleration is given by , here v is car speed along the circular path and r is radius of the curve
So
v = 12 m/sec
So speed of the car around the circular path will be 12 m/sec
Answer is: 354 days.
V = V₀ + g·t.
V - final velocity, V = 3·10⁸ m/s.
V₀ - initial velocity, V₀ = o, because spaceship is in rest.
t - t<span>ime, how long it takes for spaceship to move from one position to another.
</span>g - gravity, g = 9,8 m/s².
t = V÷g = 3,06·10⁷s = 510204min = 88503,4hr = 354 days.
Answer:
d
Explanation:
Ya gon find the Kenitic Energy first
K=½mv²===> K=½×0.2×(0.2)²===> 0.1(0.04)===> 0.004
and now the replacement:
0.004=½×0.4V²====> v²=0.02===> V=0.14m/s
