Answer:
0.17 degrees
Explanation:
From the question we are given the following:
acceleration due to gravity =
radius (r) = 6.5 cm = 0.065 m
time (s) = 9.3 s
angle = ?
- we first have to calculate the distance the water moves, and this is the circumference of the microwave
circumference = 2 x π x r = 2 x π x 0.065 = 0.408 m
- Now we find the speed with which it moves at
speed =
= = 0.044
- The next step is to find the centripetal acceleration
a =
= = 0.03
being a vector quantity, acceleration has direction, the centripetal acceleration is the x component while the y component would be the acceleration due to gravity (g)
A = 0.03 x + 9.8 y
to find the angle we can apply tan θ =
θ = 0.17 degrees
5.5m/s
Explanation:
Given parameters:
Mass of ball = 22kg
Kinetic energy = 334J
Unknown:
Velocity of the girl = ?
Solution:
Kinetic energy is the energy possessed by a moving body. It is the energy due to the motion of a body.
It is mathematically expressed as;
K.E =
Input the values;
334 = x 22 x v²
v² =
v² = 30.4
v = √30.4 = 5.5m/s
