Question

body of mass 1000 kg moving at a speed of 10 m/s reaches the speed of 50

m/s in 20s. Calculate the force required to do so.​

Answer 1

Given:-

• Mass (m) = 1000kg

• Initial Velocity (u) = 10m/s

• Final Velocity (v) = 50m/s

• Time (t) = 20s

Formula:-

Force (f) = rate of change of momentum

F = m ( v - u ) / t

F = 1000 ( 50 - 10 ) / 20

F = 1000 x 40 / 20

F = 2000N

Answer 2

Answer:

F = 2000 Newtons

Explanation:

F = m × a

m = 1000

a = $\frac{50 - 10}{20}$ m/s²

a = 2 m/s²

F = 1000 × 2 = 2000 N
