Question

Please help me as soon as possible

Answer 1

Given,

Mass of body = 10 kgs

u = 100 m/s

v = 0 m/s (since we have to stop it)

time = 10 s

We know, a = (v-u)/t = -100/10 = -10 m/(s^2)

We also know,

F = ma

==> 10*-10

= -100 N

Therefore, force required will be -100 N (100 N in opposite direction)
