Question

In how much time an object having mass of 100kg will speed up from 5m/s to 25m/s, if 500N force will be applied over it?

Answer 1

Explanation:

given in question,

m = 100kg

u = 5 m/s

v = 25 m/s

F = 500N

acceleration = Force/mass

= 500 /100

acceleration = 5 m/s2

using,

V = u+ at

25 = 5 + 5t

5t = 20

t = 4 sec

Answer 2

Answer:

given in question,

m = 100kg

u = 5 m/s

v = 25 m/s

F = 500N

acceleration = Force/mass

= 500 /100

acceleration = 5 m/s2

using,

V = u+ at

25 = 5 + 5t

5t = 20

t = 4 sec
