78*6*9.8 N = 4586.4 N
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.
The momentum is given by the formula... p=mv p=momentum m=mass v=velocity In your question your mass is 30kg and your velocity is 10m/s just do simple math and your momentum is 300kg*m/s
Meters for height Kilograms for mass.

78*6*9.8 N = 4586.4 N
use the formula W = mgs W stands for work done in joules m stands for mass of the object g stands for gravity s stands for the distance the object is lifted W = mgs W = 78kilograms•9.8m/s2•6meters W = 4586.4 J (joules) answer would be 4,586.4 J
The work done is equal to the change in potential energy, which can be calculated as (mass x gravity x height). Plugging in the values: (200 kg x 9.8 m/s^2 x 5 m) = 9800 J. Therefore, 9800 joules of work are done when the box is lifted 5 meters above the floor.
Work = Force x DistanceForce = Mass X Gravity (Near earth approximation)SoWork = 30kg x 9.8 m/s2 x 20m = 5880 joules
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.
If an object has a mass of 30 kg, its mass on Earth would also be 30 kg. Mass is a measure of the amount of matter in an object, and it remains the same regardless of the gravitational force acting on it.
The work done is given by the formula: work = force x distance. Since the force required to lift an object against gravity is equal to its weight (mass x gravity), the work done is 4.5 kg x 9.8 m/s^2 x 10 m = 441 J.
question 24 on penn foster is C.
The work done to lift the 15 kg mass is 441 J. This can be calculated by multiplying the weight of the object (15 kg * 9.8 m/s^2) by the height lifted (3 m).
6,000 J
The work done to lift the toolbox is calculated as the force (weight of toolbox) multiplied by the distance it moves (height lifted). In this case, the work done will be 6kg (mass of toolbox) * 9.81 m/s^2 (acceleration due to gravity) * 1.5m (height lifted), which equals 88.29 Joules.
