This doesn’t makes sense at all yes the sheer is ,383
Answer:
1- The lank with the least slope will be the easiest to climb because it will require the least force.
2- All three paths will require the same energy as the work done will be the same in all three cases.
Explanation:
1- Work done W = Force x Displacement i.e. W = F × cosФ where 'Ф' is the angle between force and displacement. Smaller the angle least is the force required to climb. Hence the path with least slope will be easier to climb.
2- Since W = F × cosФ as the angle increase cos Ф decrease which means the slope is increase and consequently the force required also increases but the total work done remains the same. Hence the energy required to climb all three Lanks will be the same.
Answer:
F = 3.01 N
Explanation:
Given that,
Mass of a block, m = 2.75 kg
Force applied to the block, F = 5.11 N
It is directed 53.8° above horizontal.
We need to find the total force acting on the block. The force acting on it is given by :
So, 3.01 N of force is acting on the block.
The velocity of a car with a mass of 3.1 kg is equal to 6.22 m/s
<u>Given the following data:</u>
- Kinetic energy = 60 Joules
To calculate the velocity of the car:
Mathematically, kinetic energy is calculated by using the formula;
<u>Where:</u>
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Making V the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity, V = 6.22 m/s

The sequence of energy transformations from the moment the ball is dropped to the moment the board is bent to its maximum extent and the ball is at rest is as follows:
1. The ball has potential energy (gravitational potential energy) from being held above the board.
2. As the ball is dropped, it gains kinetic energy as it accelerates to the ground.
3. When the ball hits the board, the kinetic energy is converted into elastic potential energy as the board bends.
4. As the board continues to bend, the elastic potential energy is converted into thermal energy.
5. Finally, when the board reaches its maximum extent, the ball is at rest and its kinetic energy has been completely converted into thermal energy.
