Two forces are acting on a 6.89-kg object that moves with acceleration 9.31 m/s2 in the positive y-direction. If one of the forces acts in the positive x-direction and has magnitude of 12 N, what is the magnitude of the other force in N?
1.)What force is necessary to give a 1900 kg car an acceleration of 2.5 m/s2? 2.) Find the acceleration produced by a force of 78 N acting on a 6.5 kg object. 3.) What force must be applied to a 1100 kg tractor to give it an acceleration of 2.8 m/s2?
An object experiences a net force of 20 N and has an acceleration of 4 m/s2. The object’s mass must be 20 kg 5 kg 80 kg 2 kg
An initially stationary object experiences an acceleration of magnitude 0.5 m/s2 for a time interval of 28 s. how far it will be after this time?
7. A force causes a mass of 4 kg to have an acceleration of 8 m/s2. Suppose something causes the (1 point) mass to be one-quarter of its original amount. What will happen to the acceleration if the amount of force used remains the same? It will decrease to 2 m/s2 It will remain the same. It will increase to 32 m/s2. It will increase to 16 m/s2 8. What is the force required to propel a 2.00 kg object...
10. An object initially at rest experiences an acceleration of 1.20 m/s2 for 6.10 s then travels at that constant velocity for another 8.40 s. What is the magnitude of the object's average velocity over the 14.5 s interval? m/s
10. An object initially at rest experiences an acceleration of 1.40 m/s2 for 5.40 s then travels at that constant velocity for another 9.30 s. What is the magnitude of the object's average velocity over the 14.7 s interval? m/s
A small object has a mass of 3.2 10-3 kg and a charge of -30 µC. It is placed at a certain spot where there is an electric field. When released, the object experiences an acceleration of 2.65 103 m/s2 in the direction of the +x axis. Determine the magnitude and direction of the electric field.
Three forces acting on an object are given by # = (-2.21 + 7.155) N, F2 = (4.559 – 2.55) N, and F3 = (-49.51) n. The object experiences an acceleration of magnitude 3.95 m/s2 (a) What is the direction of the acceleration? 5.6 x Note that the direction of the acceleration is the same as the direction of the net force. (counterclockwise from the +x-axis) (b) What is the mass of the object? 12.0 kg (c) If the object...
A 67 kg sprinter starts a race with an acceleration of 4.2 m/s2. m= 67 kg a= 4.2 m/s2 What is the magnitude of the net external force on him in N?
