Yes, that looks correct, if you use only the magnitudes of the vectors, i.e. the "dot" product.
Force x speed = force x (distance / time) = (force x distance) / time = work (energy) / time = power.

What is the difference between force and power?
Force is the rate of change of momentum (which is the product of mass and velocity) whereas power is the rate of work done (product of force and displacement) In fact, it can be shown that power = force x velocity
How if force related to velocity and acceleration?
An object's force (in Newtons) is the product of its velocity and acceleration: F = m x a
How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
A weightlifter raises a 90 kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
power = force x velocity velocity = distance/time = 68 x 11/3 = 2.2/0.6 = 249.3 Watts = 11/3

Write the formula for power?
Assuming you're talking electronics: Power = Voltage x Current. Or, W = V x I. Also, in physics: Power = Work/Time. Also, Power = Force x Velocity
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
How if force related to velocity and acceleration?
An object's force (in Newtons) is the product of its velocity and acceleration: F = m x a
If an electric motor develops 77 kW of power as it lifts an elevator 16 meters in 35 seconds how much force does it exert?
Energy transferred (or work done, E) is equal to force (F) multiplied by the distance moved in the force's direction, x. E = Fx Rearranging F = E/x And substituting F = power x time F = 77000 x 35/16 = 168437.5 Newtons, which is the weight of the load. This model assumes constant velocity.
How do you find tangential velocity?
Tangential velocity is equal to (mass x velocity^2)/radial distance
What equals acceleration x time?
It's equal to the change in velocity (final velocity - initial velocity).
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
Why everything to power of zero is equal to one?
x to the power a divided by x to the power b is x to the power (a - b) When a and b are equal then this is x to the power a divided by x to the power a, ie 1. x to the power (a - a) = x to the power zero. Things which are equal to the same thing are equal to each other, so 1 = x to the power zero.
How many lbs of thrust does a 50hp boat motor have?
You would need to know how fast it is going to determine the force that the 50 hp motor is pushing the boat. Energy = Force X Distance. Divide both sides by time: Energy/time = Force X Distance/Time = Force X Speed, and Energy/Time = Power, so Power = Force X Speed, and Force would equal Power/Speed.
What are equations for velocity when given force and mass?
Velocity = (velocity when time=0) + (Force x time)/(mass) ===> F = MA A = F/M V = V0 + A T
A weightlifter raises a 90 kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
power = force x velocity velocity = distance/time = 68 x 11/3 = 2.2/0.6 = 249.3 Watts = 11/3
