A cyclist is travelling at a speed of 4.0 m/s. The total mass of cycle and its rider is 128 kg. Assuming the
frictional force exerted by road negligible, calculate. (i) the value of the constant force which may stop
the cyclist in 10 s, (ii) the value of the force which may stop him at a distance of 25.6 m.

Answer: hope it helps you pls pls mark me Brainliest
Explanation:
u = 4m/s
v = 0m/s
Mass = 128 kg
t = 10 s
Acceleration = (v-u)/t
= -4/10
= -0.4 s
Force = ma
= 128 * -0.4
= -51.2 N
Distance(s) = 25.6 m
2as=v^2-u^2
2 * a * 25.6 = 0 - 16
50.12a=-16
a=-16/50.12
a=-0.3192
Force = ma
= 128 * 0.3192
=-40.85 Newton
