work = f x s. work = 1000 x 40 40000J
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
The power of the machine can be calculated using the formula Power = Work/Time. Given that Work = Force x Distance, and the force required to lift the object will be its weight (N), the power can be calculated using the force (weight of object) and the distance it is lifted in the given time frame.
A lever is a simple machine that can be used to move or turn an object. By applying a force at one end of the lever, the object at the other end can be lifted or rotated.
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 seconds.
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
The potential energy gained by the object is 1,000 Joules. Potential energy is calculated using the formula PE = mgh, where m is the mass of the object (10 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height the object is lifted (10 meters).
The speed of the object is 5 m/s. Speed is calculated as distance divided by time, so 20 meters/4 seconds = 5 m/s.

Ignoring air resistance, it would be 706 meters .
Average speed = (total distance) / (total time for the distance) =(16 + 16) / (4 + 2) = (32/6) = 51/3 meters per second
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
