(b) What is the tension in the string connecting the blocks? (See Section 4.6.) Figure WU4.13
A force F applied to an object of mass m1, produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2. (a) What is the value of the ratio m1/m2,? (b) m1 and m2 are combined into one object, find its acceleration under the action of the force F.

Please answer in units of kg. b) What TWO combinations of slowing down, speeding up, going up and going down causes the greatest force to be exerted on the fishing line?
18. In a competition, a small robot accelerates forward at 0.25 m/s? as it pushes a wood a = 0.25 m/s² block of %3D mass 1.6 kg towards a basket. A friction force of 3.7 N exists between the block and floor. a) What is the net force acting on the block? a = 0.25 m/s? b) What force is the robot applying to accelerate the block? (ANS: a) 0.4 N b) 4.1 N)
According to Newton's 1st law of motion, if the net force acting is zero, O a. a moving object increases its speed O b. a moving object continues to move with a constant velocity Ос. a moving object slowly comes to rest O d. an object at rest starts to move with a positive acceleration
A small car collides with a large truck. (a) Isthe acceleration experienced by the car greater than, less than, orequal to the acceleration experienced by the truck? (b) Choose thebest explanation from among the following:I. The truck exerts a larger force on the car, giving it the greateracceleration.II. Both vehicles experience the same magnitude of force; therefore the lightweight car experiences the greater acceleration.III. The greater force exerted on the truck gives it the greater acceleration.
