A 15 kg tricycle is accelerated by a child at a rate of 1.2 m/s2. How much force is the child applying to the tricycle?
A.15 N
B.18 N
C.19 N
D.21 N
Prajji:
force=mass.accelaration
force = mass × accelaration ... apply this formula on it ...
mass=15 kg..acc..=1.2 .force=m×a 15×1.2=18
we know that newton's second law is f= ma where a is acceleration and m is mass and f is force so we can calculate the force. si that's the concept of this questions . i hope it helps.

Hey!
____________
Mass = 15 kg
Acceleration = 1.2 m/s^2
Force = ?
We know,
Force = Mass × Acceleration
Force applied = 15 × 1.2
Force applied = 18 N

18N
18n means
18 n
means
18Newton
F=ma
18n
yes
very nice analasis
Thanks ^^

Hi there !!
Here's your answer
The correct Option is (B) 18N
Method:
Given,
Mass of tricycle (m) = 15kg
Acceleration (a) = 1.2m/s²
We know,
Force = mass × acceleration
F = ma
F = 15kg × 1.2m/s²
F = 18kgm/s²
F = 18N
