power=work done/time interval
You can't. The mass is irrelevant to velocity. You need the distance.
The dimension of power is (energy / time)= (force x distance) / time= (mass x distance / time2) x distance / time= mass x distance2 / time3= ML2T-3
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
You cannot. Force is mass times acceleration. You have neither.
You can't. Work is (force) times (distance), so you have to know something about the force. Just knowing the mass doesn't tell you anything about the force ... unless there's actually something else about the mass that you've overlooked.
To calculate work done when given mass and power, you need to know the force applied and the distance over which the force is applied. Work done is calculated as the product of force, distance, and the cosine of the angle between them. Power is the rate at which work is done, so you can calculate it by dividing the work done by the time taken to complete the work.
To solve this, first use the formula for potential energy, to see how much energy the hero needs. Potential energy = mgh (mass x gravity x height), where the gravity is 9.82.Then divide the energy by the time, to get the power in Watts.

F=ma, where F is force, m is mass, and acceleration is a. F/a=m

To solve work and kinetic energy problems effectively, you can follow these steps: Identify the given values such as mass, velocity, and distance. Use the formulas for work and kinetic energy: Work force x distance and Kinetic Energy 0.5 x mass x velocity2. Substitute the values into the formulas and solve for the unknown variable. Pay attention to units and make sure they are consistent throughout the calculations. Double-check your calculations to ensure accuracy. By following these steps, you can effectively solve work and kinetic energy problems.
It is not clear what you want to solve for.
Kinetic energy (not power) is given by 1/2 x Mass x Velocity2
Catapult and not canapult. Any way for a given energy as mass of the object increases then distance would get decreased as velocity gets reduced.
The strength of gravitational pull of any given heavenly body is primarily determined by its mass and distance from other objects. The greater the mass of the body and the closer it is to another object, the stronger the gravitational pull will be.
You cannot. Force is mass times acceleration. You have neither.
