Question
Answer
If a 10 kilogram object accelerates Given: m = 10 kg
suddenly at 15 m/s2, how much
a = 15 m/s2
force was applied to the object?
Asked: F?
Answer:
F= m × a
F = 10 × 15
F = 150 N
The force was applied to the
object is 150 N.
You’re at rest on an ice rink when
you get hit from behind with a
force of 165 N as someone bumps
you. If your mass is 55 kg, what is
your acceleration?
Given: F = 165 N
m = 55 kg
Asked: a?
Answer:
F=m×a
F
a= m

165
a = 55
a = 3 m/s2
The acceleration is 3 m/s2.

Calculate the acceleration of the
object below?
Given: ƩF = 45 - 25 N = 20 N
m = 2 kg
Asked: a?
Answer:
ƩF = m × a
ƩF
a= m

a= 2
a = 10 m/s2
The acceleration of the object
is 10 m/ s2.
