Question

a 2 kg book accelerated at 5m/s² for 50 cm across a frictionless table. how much work was done on the book?​

Answer 1

Answer:

5 Joule

Explanation:

mass = 2kg, acceleration = 5m/s2,

Distance = 50cm = 0.5m

since,

Work done = Force × Displacement

so,

Work = (mass×acceleration) × D

Work = 2 × 5 × 0.5 = 5 J

Hope it helps u

Answer 2

Answer:

Work done on the book is 5 J
