Answer:
a) 9.46M m/s^2
b) 48.83m
c) 68.22m/s
Explanation:
The centripetal force must be equal to the horizontal component (x component) of the gravitational force over the plum bob. Thus, we have
( 1 )
where M is the mass of the car, v its speed, r the radius of the curvature and g the gravity constant.
a) By replacing we obtain:
( 2 )
where it is only necessary to put the mass of the car M in (2).
b) By canceling M in (2) and taking apart r we get:
c) If the angle is 7° the speed is given by:

Answer:
12.5 m/s
Explanation:
In a acceleration time graph the area under the curve gives the change in velocity of the object. Here object starts at rest and therefore initial velocity is 0. After 5 seconds acceleration is 5m/s2.
change in velocity=area under the curve
change in velocity= 0.5*acceleration* change in time
v-0=0.5*5*5
v=12.5 m/s

Answer:
1.31498 kg
0.72050 s
0.72050 s
Explanation:
m = Mass of block
g = Acceleration due to gravity = 9.81 m/s²
k = Spring constant = 100 N/M
x = Displacement = 0.129 m
The force balance is
The mass of the block is 1.31498 kg
Time period is given by
The period of oscillations is 0.72050 s
The time period does not depend on the acceleration due to gravity. It varies with the mass and the spring constant.
Hence, the time period would be the same
