F = 15 N

F = 15 N m = 2 kg

F = 15 N m = 2 kgg = 9.8 m/s2

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × s

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N 3. Work done against the force due to gravity,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N 3. Work done against the force due to gravity,

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N 3. Work done against the force due to gravity, W = Fs cosΘ

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N 3. Work done against the force due to gravity, W = Fs cosΘW = 19.6 × 5 × cos 30°

F = 15 N m = 2 kgg = 9.8 m/s2s = 5 m 1. Work done by the force in pulling the body, W = F × sW = 15 N × 5 m = 75 J 2. Force due to gravity on the body, F = m × g F = 2 × 9.8 = 19.6 N 3. Work done against the force due to gravity, W = Fs cosΘW = 19.6 × 5 × cos 30°W = 49 J

Work done against the force due to gravity, W = Fs cosΘW = 19.6 × 5 × cos 30°W = 49 J Now as the body is pulled along an inclined plane making an angle of 30° the work done on the body will be less than the work done on the body while pulling it vertically upward.

Answer 2

Answer:

F = 15 N

m = 2 kg

g = 9.8 m/s2

s = 5 m

1. Work done by the force in pulling the body,

W = F × s

W = 15 N × 5 m = 75 J

2. Force due to gravity on the body,

F = m × g

F = 2 × 9.8 = 19.6 N

3. Work done against the force due to gravity,

W = Fs cosΘ

W = 19.6 × 5 × cos 30°

W = 49 J

        Now as the body is pulled along an inclined plane making an angle of 30° the work done on the body will be less than the work done on the body while pulling it vertically upward.
