Question 1 The first question does not require the coefficient of friction. Doesn't all the work being performed by the system = friction? Friction is the only thing that is performing work? Transformer CombatMegatron's primary weapon is a mounted canon that uses fusionto generate its output energy.a) If Megatron shoots Starscream (mass of 10,000 kg),and Starscream is knocked back and slides 25.5 m from the blast.He was initially sliding back at 10 m/s.

Which of the statements below is true when you catch a baseball that comes at you horizontally? a. The work that you do is positive. b. The work that you do is negative. c. Work is not a vector and cannot be referred to as positive or negative. d. Work is a scalar product expressed in terms of magnitudes, so it is never negative. e. Work is expressed in terms of kinetic energy, which must be positive.
How do you know if the work done by a force acting on an object is positive or negative? Hint: Work is a scalar but both force and displacement are vectors.
The only force acting on a 2.0 kg canister that is moving in an xy plane has a magnitude of 5.7 N. The canister initially has a velocity of 4.5 m/s in the positive x direction, and some time later has a velocity of 4.8 m/s in the positive y direction. How much work is done on the canister by the 5.7 N force during this time? Number i Units
Which of the following statements are true? Select all correct. Question 3 options: If an object speeds up, then the total work done on the object was positive. If an object moves at a constant speed, then the work done by each individual force is zero A force must be parallel to the displacement to do any work. If a force is perpendicular to displacement, it does zero work. If a force has a component in the opposite direction of the displacement, it does positive work. If an object doesn't move, then the work done by every individual force must be zero.

6. A force and a displacement are given in component form. What is the work done by this force? F =(si+2j+k)N Ar=(2i-3 +2%)m 24 )m
Assertion: When the force retards the motion of a body, the work done is negative. Reason: Work done depends on angle between force and displacement. 1) Both assertion and reason are true and reason is the correct explanation of assertion. 2) Both assertion and reason are true but reason is not the correct explanation of assertion. 3) Assertion is true but reason is false. 4) Assertion is false but reason is true.
