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

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.

You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
