work done is = to force multiply by displacement
here force is = 1000x10 N
and dispacement is 75m
= 75x104
1
1400j
700 x 4 = 2,800 newton-meters = 2,800 joules
78*6*9.8 N = 4586.4 N
1000
1000 m in a KM Kilo means 1000 so kilometer is 1000 meters :)
a fallen treee is lifted 2.75 meters. How much work is done?
work = f x s. work = 1000 x 40 40000J
2 Newton-meters
1400j
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
700 x 4 = 2,800 newton-meters = 2,800 joules
Work = force * distance Work = 23N * 2.3 meters = 53 Joules of work is done ==================
The total work done on the object, from beginning to end of that scenario, is equal tothe change in the object's potential energy from beginning to end, which is zero.
100 x 3 = 300 joules
78*6*9.8 N = 4586.4 N
