Question

A toy car has a mass of 3 Kg is pushed horizontally with a force of 3 N. Friction is so small it can be ignored.

What is the acceleration?

How fast is it going after 8 s if it starts from rest?
How far did it go?

Answer 1

Step-by-step explanation:

• Mass = 3kg
• Force=3N
• Acceleration= Force/mass
• =3/3
• =1 m/s²

• v=u+at
• v=0+1(8) (At rest)
• v=8m/s

• Displacement = velocity× time
• Displacement=8×8 m
• Displacement=64m
