If i thought about this properly the answer is b
Answer:
1)force:- force is an external affert by any body on an object.
2) force and motion are related to each other. force helps to create motion in any object.
3) frictional force
4) Newton
1. After the collision, their velocities have switched. This is Newton's third law of motion.
2. The total momentum is conserved.
3. The same thing would happen if the collision is totally elastic.
For 4 and 5.
Using the conservation of momentum equation
m1v1 + m2v2 = m1'v1' + m2'v2'<span />
Answer:
The constant angular acceleration of the wheel is 12.16 rad/s²
Explanation:
Given;
initial angular distance, θ = 28
time of the motion, t = 5 s
initial angular velocity is calculated as;
final angular velocity is given as,
The constant angular acceleration is calculated as;
Therefore, the constant angular acceleration of the wheel is 12.16 rad/s²
