In a Physics lab, Nene and Nono apply a rightward force to a 4.52-kg cart to accelerate it across a horizontal surface at a rate of 1.28 m/s², the coefficient of kinetic friction between the cart and floor is 0.43. a. Determine the normal force on the cart. b. Determine the friction force acting upon the cart. c. Determine the applied force on the cart.

8. Which of the following is false in regards to pulling an object across the floor with a rope above the horizontal? a. The normal force on the box will be larger than its weight b. The object will experience a smaller force of friction The normal force on the box would be the force of gravity subtracted from the y-component of the rope а. с. d. All of the above statements are false . An object is shot directly upwards at 7.0 m/s. How long will it take to travel 12 a. 19 b. 0.sis d. 1.is e. 24 e. None of the above statements are false

Force causes acceleration. choose all the correct answers when  non zero net force acts on the object.   A. An object starts at rest and moves with a velocity of 45mph in 5 sec.   B. An object is moving with uniform velocity.   C. An object is at rest.   D. An object moves around a circle.

1. A car of mass M goes over a semi-circular hill of radius R. At the time shown the car has a speed v, and is speeding up at a rate g/3 which is larger than g sin . Assume the car does not lose contact with the ground. +x a. Draw the free body diagram showing the forces acting on the car. b. Write out Newton's 2nd law in the x and y directions as shown using the names of the forces in the FBD, and vo, R, 0, and/or g. Use the coordinate system shown. X: y: c. What is the normal force acting on the car in terms of M,0, vo, R, and/or g? d. What is the friction force acting on the car? e. How fast would the car have to be traveling at if it just lost contact with the ground at the point shown?
