Question

when an object travels in uniform velocity and hits a wall.... is the force exerted on the wall zero by the object??
bcos f=ma
a=0 in uniform velocity
f=m*0
f=0

??? pls ans correctly

Answer 1

Answer:

f= ma

correct

Explanation:

but the wall has more mass than the object and

the force applied by the object is not enough to move the wall

the friction and wall's mass applies the force

with same magnitude that the object applied

hence both forces cancels each other out.

net force becomes = 0
