Give reasons for the following-
(a) We tend to slip when we step on a banana peel.
(b) It is easier to push a lighter box than a similar heavy box on the same floor.
(c) The force, needed to start a cart, is (somewhat) greater than the force
needed to keep it moving with a uniform speed.
(d) Sportsmen use shoes fitted with spikes.

Answer:
a) as the surface becomes smooth and friction decreases.
b)as less friction will be applied by the floor.
c) as it is difficult to start a object to move.
d) to increase friction

(A) we slip on banana peel due to less force between the our feet and the peel.
(b)it is easier to ouch lighter box than heavier box because less force is required to ouch lighter box whereas more force is required to ouch heavy box.
(C)the force needed to start a Cart is greater than the force needed to keep it moving at a uniform speed because we apply plenty of force first and then the cart comes in motion so little force is required to keep it moving at a constant speed.
(D)sportsmen use shoes with spikes so that they don’t slip from the ground. As the spikes increase the frictional force between the ground and our feet.
These are the answers hope it helps pls mark as brainliest.
