5) An object is moving to the left at constant velocity. A constant force to the left is now applied to the object. Which of the following is correct? A) The object continues to move to the left, and its speed increases. B) The object continues to move to the left with a constant speed.

answer all please 1 If a 71-kg astronaut at rest in space throws a ball with mass 0.61 kg at a speed of 12 mph. What happens to the astronaut as a result? 4 A moving ball collides elastically with another ball that is twice as heavy and is initially at rest. What happens to the lighter ball as a result of the collision? (a) She picks up some of the movement of the ball, causing her to move forward....
every question on a solo paper 1) 4. A charged particle A exerts a force of 2.62 uN to the right on charged particle B when the particles are 13.7 mm apart. Particle B moves straight away from A to make the distance between them 17.7 mm. What vector force does it then exert on A? 1) 4. A charged particle A exerts a force of 2.62 uN to the right on charged particle B when the particles are 13.7...
3.) A 60.0 kg box is pulled by a 275 N force of tension provided by a rope pulled at an angle 30.0 degrees above the horizontal. The box moves 25.0 m horizontally as it is pulled by the rope. The coefficient of friction between the box and the ground is uk-0.20 a.) How much work does the rope do on the box? (5 pts) b.) How much work does friction do on the box? (5 pts) c.) How much...
The makers of a child's swing set claim that the average assembly time is less than 2 hours. A sample of 35 assembly times (in hours) for this swing set is given in the table below. Test their claim at the 0.10 significance level. (a) What type of test is this? This is a two-tailed test. This is a right-tailed test. This is a left-tailed test. (b) What is the test statistic? Round your answer to 2 decimal places. tx...

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...
2) Rita is in an elevator that is moving at a constant velocity downward. If the elevator now experiences an acceleration so that it speeds up, the normal force Rita experiences A) becomes greater than her weight. B) remains equal to her weight. C) becomes less than her weight, but not equal to zero. D) becomes zero. E) cannot be determined without more information. 11) A rope connects object A (mass 4m) with object B (mass m). (Object A is...
