1) On its own, a tow truck has a maximum acceleration of 4.53-m/s?. What will be its maximum acceleration when the truck is using a light horizontal chain to tow a bus of 2.4 times its own mass? âMAX= 2) A net force of 121-N is applied to a certain object. As a result, the object accelerates with an acceleration of 21.2-m/52. what is the mass of this object 3) P Flag question If I weigh 792-N on Earth at a place where g = 9.80 m/s2 and 5583-N on the surface of another planet. What is the acceleration due to gravity on that planet? gplanet= 4) What force is needed to accelerate a sled (mass =75.8-kg) at 2.6-m/s2 on horizontal frictionless ice? F= 5) A human stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.79 of their regular weight. Calculate the acceleration of the elevator. a= 6) A 1525-kg sports car accelerates trom rest to 134.2-km/h in 5.81-S. What magnitude force does a 69.6-kg passenger experience during the acceleration? 7. A 19.6-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.622, and the coefficient of kinetic friction is 0.200. What horizontal force must be applied to the box to cause it to start sliding along the surface? Fx= 8) A 180-N crate is being pulled up a perfectly smooth ramp that slopes upward at 16.0° by a pull that is directed at 31.0° above the surface of the ramp. What is the magnitude of the pull required to make the crate move up the ramp at a constant velocity of 1.75 m/s?
