Question

1) Four Golf Balls sit in the middle of a stationary truck's bed. What happens to the golf balls when the truck accelerates Explain using Newton's 1st Law.

4) Pick the best definition of the necessary conditions for equilibrium:

  1. No movement
  2. Constant linear movement
  3. Constant linear acceleration
  4. 1 or 2
  5. 2 or 3

5) Which of the following statements is true?

  1. A pendulum hanging at rest has a normal force acting in the +y direction.
  2. A pendulum hanging at rest has no normal force acting on it.
  3. A pendulum hanging at rest has a normal force acting in the +x direction.(perpendicular to the string)
Expert Solution
Step 1

Given,

Four golf ball on stationary bed of truck 

Step 2

(1) 

According to newton second law 

∑ F=ma

so when truck moves with acceleration then golf ball experience a psuodo force and which move them backwards.
