Answer:
16.87 m/s
Explanation:
To find the speed of the car at the top, when the normal force is equal the gravitational force, we just need to equate both forces:
is the centripetal acceleration in the loop:
So we have that:
So, using the gravity = 9.81 m/s^2 and the radius = 29 meters, we have:
The speed of the car is 16.87 m/s at the top.
Answer:
T = 29.6 N
Explanation:
length of the rope is
L = 18 m
mass of the rope is
m = 12 kg
now we have
mass per unit length of the rope is given as
[te]\lambda = \frac{12 kg}{18 m}[/tex]
now time taken by wave to reach from end to other
now we have
so we will have
Answer: Given: h₀=5cm
p=30cm
hi
f=45cm
require: q=?
hi=?
formulas:
1/f=1/p+1/q
hi/h₀=q/p
calculations:1/q=1/f-1/p
1/q=1/45-1/30
1/q=0.022=0.033
1/q= = -0.011
q=1/-0.011
q= -90.91cm
hi=p × h₀/q
hi=30ₓ5/-90.91
hi=150/-90.91
hi= -1.65cm
