Answer:
The change in momentum is
Explanation:
From the question we are told that
The mass of the probe is 
The location of the prob at time t = 22.9 s is 
The momentum at time t = 22.9 s is
The net force on the probe is 
Generally the change in momentum is mathematically represented as

The initial time is 22.6 s
The final time is 22.9 s
Substituting values

The answer might be C ? hope it's right
Answer:
80m
Explanation:
u=20,R=?,sin theta=1,g=10
R=u²sin2theta/g
R=20²x2/10
R=400x2=800/10
R=80m
Answer:
The correct answer is Option A.
Answer:
10.09 N
Explanation:
Analogously to Newton's second law, torque can be defined as:

Here, I is the moment of inertia and
is the angular acceleration. We have:

Torque is the vector product of the position vector of the point at which the force is applied by the force vector:

Since the effective lever arm is perpendicular to the force, the angle between them is
. The magnitud of this vector product is defined as:
.
Solving for F and replacing the known values:
