A body with mass of 7.5 Kg is accelerated by a horizontal force F = 2.0 N from rest . What is velocity of this body after 5.0 s of motion?

A net force of 8.0 N gives a mass of m1 kg an acceleration of 2.0 m/s2 and a mass m2 kg, an acceleration of 4.0 m/s2. What acceleration would the force give the two masses if they were fastened together?

A flea jumps by exerting a force of 1.02 10-5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.20 10-6 N on the flea. Find the direction and magnitude (in m/s2) of the acceleration of the flea if its mass is 6.0 10-7 kg. (Let us assume that Fwind points to the right. We will consider this to be the +x direction and vertical to be the +y direction.) magnitude m/s2direction ° (measured clockwise from the vertical)

Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of thè pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 3.70 kg) moves is frictionless. The system is released from rest, and block B (mass 6.00 kg) moves Part A What is the tension force that the rope exerts on block B? downward 1.80 m in 2.00 s.
