Question

A body of mass 1000kg at speed of 10m/s reaches he speed of 50m/s in 20 s calculate the force re quired to do s

Answer 1

Answer:

2000 N

Explanation:

F = ma

a = v - u / t

Initial velocity = 10 m/s

Final velocity = 50 m/s

Time = 20 s

a = 50 - 10 / 20

= 40/20

= 2 m/s²

F = ma

= 1000 × 2

= 2000 N

Answer 2

Explanation:

F=ma

a=(v-u)/t

=(50-10)/20

=40÷20

=2 m/s^2

so,F=1000×2=2000N
