Question

Kinetic energy of a body is 300 joules force on 25 newton is applied to stop it.calculate the distance travelled by the body before comes to rest? Please answer ASAP

Answer 1

kinetic energy = work done by body
                  given, kinetic energy = 300 J
                            force act on body = 25 N
but we know,
work done by body = force act on body × distance travelled by body along force e.g., W = f.s [ where s is distance travelled by the body ]
                         
now, 
K.E = W
300J = 25N × s
s = 300/25 = 12 m
hence, distance travelled by body = 12m 

Answer 2

Answer:

12m

Explanation:

kinetic energy = work done by body

                 given, kinetic energy = 300 J

                           force act on body = 25 k

but we know,

work done by body = force act on body × distance travelled by body along force e.g., W = f.s [ where s is distance travelled by the body ]

                         

now,  

K.E = W

300J = 25N × s

s = 300/25 = 12 m

hence, distance travelled by body = 12m
