Question

A force of 10 newtons accelerates an object from 15 to 25 meter per second square in 20 seconds . Calculate the mass of an object

Answer 1

hey
___________

F =10N
a=?
m=?
acceleration = change in velocity / time taken

a = v-u/ time taken
a= 25-15/20
a=10/20
a=1/2=0.5

F =m×a

10= 0.5×m
10×10/5 = m
100/5 = m
20 kg = m

hope helped

Answer 2

Answer:

$\fbox\red{Verified Answer:-}$

Force - 10 N

Force - 10 Na=?

Force - 10 Na=? m=?

Force - 10 Na=? m=? a=v-u/t

Force - 10 Na=? m=? a=v-u/ta= 25-15/20

Force - 10 Na=? m=? a=v-u/ta= 25-15/20.: a=0.5 Or 10/5

Force - 10 Na=? m=? a=v-u/ta= 25-15/20.: a=0.5 Or 10/5F=ma

Force - 10 Na=? m=? a=v-u/ta= 25-15/20.: a=0.5 Or 10/5F=ma10=m×10/5

Force - 10 Na=? m=? a=v-u/ta= 25-15/20.: a=0.5 Or 10/5F=ma10=m×10/5.: m = 10×10/5

Force - 10 Na=? m=? a=v-u/ta= 25-15/20.: a=0.5 Or 10/5F=ma10=m×10/5.: m = 10×10/5m=20 kg ans....
