Force and Acceleration Worksheet
1. The following 10 kg box is being pulled with a net force of 100 N
100 N
(a) What is the acceleration of the box?
2. Use the following diagram to help answer the following questions.
Friction
Pull
(a) Suppose you pull on the box with 5 N of force. The box moves at constant
velocity. What is the friction force?
(b) Suppose you pull on the box with 10 N of force. If the friction force remains
constant what is the net force on the box?
(c) If the box weighs 5kg what is the acceleration on the box?
3. Use the following diagram to help answer the following questions.
Air Resistance
Weight
(a) What is the weight of the10 kg box?
(b) Suppose while falling the 10 kg package reaches terminal velocity. What is
the force of air resistance?
4. Suppose a 25 kg box sits on a table as shown in the diagram.
Weight
(a) If the box is 0.25 m long and 0.25 m wide what is the area of the box?
(b) What is the pressure that the box exerts on the table?
5. Calculate the acceleration of a 2000-kg, single engine airplane just before takeoff
when the thrust of its engine is 500 N.
6. Calculate the acceleration of a 300 000-kg jumbo jet just before takeoff when the
thrust of each of its four engines is 30 000 N.
7. Calculate the horizontal force that must be applied to a 1-kg puck to make it
accelerate on a horizontal friction-free air table with the same acceleration it
would have if it were dropped and fell freely.
a=g
Weight
8. Calculate the horizontal force that must be applied to produce an acceleration of
1.8g (1.8 x 9.8 m/s2) for a 1.2-kg puck on a friction-free air table.
9. An occupant of a car has a chance of surviving a crash if the deceleration during
the crash is not more than 30g (30 x 9.8 m/s2). Calculate the force on a 70-kg person
decelerating at this rate.
