A body of mass 10km is acted uponed by a constant force of 30N for 2second calculate Kinetic energy gained by the body

Kinetic energy gained by the body = (1/2) × 10 × (30 × 2)^2 = 1800 J

Did you know?

Did you know that the kinetic energy gained by a body can be calculated using the formula KE = (1/2)mv², where KE represents kinetic energy, m represents mass, and v represents velocity? In the given scenario, a body with a mass of 10kg is acted upon by a constant force of 30N for a duration of 2 seconds. To calculate the kinetic energy gained by the body, it is essential to determine the final velocity. By using the equation F = ma (Force = mass × acceleration), the acceleration can be obtained as a = F/m = 30N/10kg = 3 m/s². By utilizing the equation v = u + at (final velocity = initial velocity + acceleration × time), assuming the initial velocity as 0 (since it is not provided), the final velocity comes out to be v = 0 + 3 m/s² × 2s = 6 m/s. Plugging the values into the kinetic energy formula, KE = (1/2)mv², results in KE = (1/2) × 10kg × (6 m/s)² = 180 Joules. Therefore, the body gains 180 Joules of kinetic energy in this scenario.
