Answer:33.58794 m/s
Explanation : fCenrtipetal force = mv2/r
m = Mass of car
r = Radius of curvature = 115 m
g = Acceleration due to gravity = 9.81 m/s²
The normal force is given by
N=Fc+mg
At the bottom N = 2N
2mg=fc+mg
⇒2mg=mv2
The car was traveling at the speed of 33.58794 m/s
Answer: 3 cm. ... mass per unit length of 0.05 kg/m and a tension of 80 N has an amplitude of 5 cm. ... W2 28 °s The wave function for a harmonic wave on a string is y(x, t) = (0.001 m) ... (a) What average power is transmitted along the wire if the frequency is 400 Hz? (b) ...
Explanation:
Answer:
ans: 6 m/s
Explanation:
spaceship 1 has mass= 150kg
initial momentum of spaceship 1 = 900 kg•m/s
we know,
momentum = mass × velocity
so,
velocity = momentum/mass
= 900 / 150
= 6 m/s
since we know it was initial momentum so, velocity is initial speed,
Answer: 800 km/h
Explanation:
Use equation for average speed
V=S/t
where S is distance
t is time
S=4800Km
t=6h
---------
V=S/t
V=4800Km/6h=800 Km/h
