An object of mass 400 kg is located at < 86, -25, 0> m is moving at a velocity of < 6, -9,0> m/s. Two forces F₁ and F₂ are applied on the object. The net force of < 90, -75,0> N is applied for 13 s.

A block of mass m,- 13.4 kg is on a frictionless table to the left of a second block of mass m,- 21.7 kg, attached by a horizontal string (see the figure below). HINT F (a) If a horizontal force of 2.13 x 102 N is exerted on the block m, in the positive x-direction, use the system approach to find the acceleration (in m/s) of the two blocks. m/s2 (b) What is the tension (in N) in the string connecting the blocks?

A cat had a mass of 1000 kg and accelerates at 2 m/s^2. What bet force is exerted on the car?

the position of a 2-kg mass is given by x=2t^3-2t^2+5t. What is the net force on the mass at t=0 and t=1? (use m/s^2)

A car of mass 1650 kg is proceeding along a straight, level roat at 16m/s. The speed limit changes and the car accelerates for 7.5 seconds to a velocity of 48m/s. Find the net force propelling the car

Object 1 has a mass = 9000 kg. Object 2 has a mass = 8000 kg. If the m1m2gravitational force between them is 1 N, find the distance between them.

A boat with mass of 5.8 * 103 kg is traveling at 9.1 * 10' m/s. What is the magnitude of the force required to stop the boat if it undergoes a displacement of 7.4 * 10' m? Express your answer in Newtons. Answer:

Suppose one's hand exerts a force of 15 N upward on a book weighing 12 N. The reaction to the force of the hand on the book is a force of12 N exerted by the book on the hand.3 N exerted by the book on the hand. 15 N exerted by the book on the hand.12 N exerted by the book on the Earth.10 N exerted by the Earth on the book.
