Question

An object moves with an accelation of 2mpersec if its initiqk speed is 10mpersec rind its sp3ed 5 sec lste4

Answer 1

a=2 m/s
t=5 sec
u=10m/s
that u put the equation

Answer 2

1st case:-
10 m/s for 5 seconds
s = vt
= 10×5
= 50m
2nd case:-
5 m/s for 10 seconds
s = vt
= 5×10
= 50 m
Average velocity = total distance/total time
= 50+50/5+10
= 100/15
= 6.66 m/s
