A 4000 kg car is traveling right at 10 m/s. Six seconds later it is traveling right at 40 m/s. Find the net force acting on the car

A flea jumps by exerting a force of 1.35 x 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.660 x 107 N on the flea. Find the direction and magnitude of the acceleration of the flea its mass is 5.70 x 10 +y-direction is up.) kg. Do not neglect the gravitational force. (Assume that the breeze blows in the +x-direction and that the magnitude direction m/s2 x ° counterclockwise from the +x-axis

A 4.0 x 103 kg motor boat starts from a dock and begins to accelerate under a 2.0 x 104 Nforward force provided by its engines. If the boat's motion is retarded by the water with a6.5 x 103 N force of friction, what is its acceleration?

A 2.00-kg block is placed on top of a 5.00-kg block. The coefficient of kinetic friction between the 5.00-kg block and the surface is 0.200.

(b) Find force F that makes both blocks moving to the right with a = 3.0 m/s² 2.00 kg 2 (C) Find the coefficient of static friction between both blocks that prevents the 2.00-kg block to slide down when both blocks is moving with a = 3.0 m/s² 5.00 kg S F

A m1 = 5.01-kg block is placed on top of a m2 = 10.0-kg block (figure). horizontal force of F = 45.0 N is applied to the 10.0-kg block, and the 5.01-kg block is tied to the wall.

A 3.00-kg object is initially moving northward at 15.0 m/s. Then a force of 15.0 N, toward the east, acts on it for 6.00 s. At the end of the 6.00 s, what is magnitude of the object’s final velocity?

A 1200 kg speedboat is travelling East at a constant speed of 30 m/s. A 50 kg rowboat is travelling West at a constant speed of 5 m/s. Which boat has the greater net force on it? Explain using physical reasoning.

A 3.45-kg object is moving in a plane, with its x and y coordinates given by x = 3t2 - 3 and y = 2t3 + 4, where x and y are in meters and t is in seconds. Find the magnitude of the net force acting on this object at t = 2.50 s.
