Answer:
Gravity (perhaps)
Explanation:
Without a further description or a diagram, I would guess the downward force would be gravity.
The kinematics of the uniform motion allows us to find the final position vector
r = (-41.575 i + 42.253 j) m
Given parameters
- the starting position x = -17.5 m y = 23.1 m
- jump time t = 10.7 s
- The average velocities vₓ = -2.25 m / s and v_y = 1.79 m / s
to find
The uniform motion occurs when the velocity of the bodies is constant, in this case the relationship can be used for each axis
v =
x = x₀ + v t
Where vₓ it is the velocity, x the displacement, x₀ the initial position and t the time
Let's set a reference system with the horizontal x-axis. Regarding which we carry out the measurements
X axis
we look for the final position
x = x₀ + vₓ t
x = -17.5 -2.25 10.7
x = -41.575 m
Y Axis
we look for the final position
y = y₀ + v_y t
y = 23.1 + 1.79 10.7
y = 42.253 m
In conclusion, using the kinematics of uniform motion, find the final position vector
r = (-41.575 i + 42.253 j) m

Answer:
Explanation:
Given data
Mass m=5 kg
Moment of Inertia I=0.0648 kg.m²
Radius r=0.18 m
Linear Speed v=4.8 m/s
To find
Total Kinetic Energy K.E
Solution
The total kinetic energy K.E can be found as below
First we need to find the angular speed ω
So
Substitute the angular speed and given values to find total kinetic energy
So
