A truck on a flat road accelerates from rest at a constant rate and covers a distance of 100 m in 6 s. The mass of the truck is 1000 kg.  a) What is the acceleration of the truck?  m/s2 b) What is the net force on the truck?  N The truck is now loaded with heavy equipment and has a NEW total mass of 1400 kg. If the same net force is applied to the car as calculated above, then what would be the new acceleration of the truck?  m/s2 c) With this new acceleration, how much time would it take the (heavier) truck to travel 100 m starting from rest?  s d) What would be the speed of the (heavier) truck when it reaches this point?  m/s

You have landed on an unknown planet, Newtonia, and want to know what objects will weigh there. You find that when a certain tool is pushed on a frictionless horizontal surface by a 12.9 N force, it moves 16.9 m in the first 2.40 s, starting from rest. You next observe that if you release this tool from rest at 11.0 m above the ground, it takes 2.78 s to reach the ground Part A What does the tool weigh on Newtonia? Express your answer in newtons.   Part B What would it weigh on Earth? Express your answer in newtons.

A 3.6 kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 3.7 m/s2, find the force exerted by the rope on the bucket.N

In researching the forces that act on flying birds, scientists studied the motion of cockatiels’ bodies as they fly in horizontal flight. As the birds beat their wings, their bodies move up and down. Given is the vertical acceleration of a cockatiel’s body during one wing beat, consisting of an upstroke followed by a downstroke. a. If the bird’s mass is 87 g, what is the maximum net vertical force exerted on the bird?b. The bird is held in level flight due to the force exerted on it by the air as the bird beats its wings. What is the maximum value of this force due to the air?

An object of mass 0.77 kg is initially at rest. When a force acts on it for 2.9 ms it acquires a speed of 12.7 m/s. Find the magnitude (in N) of the average force acting on the object during the 2.9 ms time interval. (Enter a number.) N
