The correct answer to this qustion is velocity and time
The gravitational pull is weaker.
Answer:
3.4 Joules
Explanation:
the KE= 1/2 mv^2
By the equation v^2 = u^2 + 2as
where v is the final velocity
u is the initial velocity=0
a is the acceleration=-9.81
s is the displacement = 3.25-1.5=1.75(downwards)=-1.75
v^2= 2(-9.81)(-1.75)
v^2=34.335
KE: 1/2(0.2)(34.335)
=3.4335
=3.4 Joules( rounded to 1 decimal places)
Velocity
if you change direction, say turn around, so does your velocity
an increase in velocity is called accelleration
Answer:
Explanation:
From the given information:
The torque produced due to the force can be expressed as:

where;
= torque
F = force exerted
r = lever's arm radius
= 
= 60 N.m
However, equating the torque with the moment of inertia & angular acceleration, we use the equation:
= I∝
60 Nm = I × 120 rad/s²
I = 60 Nm/120 rad/s²
I = 0.5 kg.m²
