V=U+AT

we get the speed at 10s is 7m/s and the distance traveled can be found out by using

S=UT+1/2AT^2.

which is 60 meters .

acceleration, a= 0.2 m/s

time taken, t= 10s

speed of the motorcycle after 10 s, v = u + at

= 5 + 0.2 × 10

= 5 + 2

v = 7 m/s

distance, s = ut + 1/2 at²

= 5 × 10 + 1/2 × 0.2 × 10 × 10

= 50 + 1/2 × 20

= 50 + 10

s = 60 m
