Question

A particle of mass 5kg starts moving with an initial velocity 10 m/s under the action of force varies with time as shown in the fig. find final speed of the body when t=15 sec​

Answer 1

Answer:

3.3 is the final speed of the partical

Answer 2

Explanation:

m=5kg

u=10m/s

t=15

v=?

f=mv

f=5*10

f=50

f=ma

50=5*a

a=50/5

a=10

v=u+at

v=10+10*15

v=160m/s
