Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N.

When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation: v2x =(2P/m)*twhere P=3.6×104 W is the car's power output, m = 1200kg is its mass, and vx is in m/s. That is, the square of the car's velocity increases linearly with time Find a symbolic expression, in terms of P, m, and t, for the car's acceleration at time t.
When a click beetle is upside down on its back, it jumps upward by suddenly arching its back, transferring energy stored in a muscle to mechanical energy.This launching mechanism produces an audible click, giving the beetle its name.Videotape of a certain clickbeetle jump shows that a beetle of mass m = 4.0 * 10-6 kg moved directly upward by 0.77 mm during the launch and then to a maximum height of h= 0.30 m. During the launch, what are the average magnitudes of (a) the external force on the beetle’s back from the floor and (b) the acceleration of the beetle in terms of g?

A freight train consists of two 9.00 ✕ 105 kg engines and 50 cars with average masses of 3.50 ✕ 105 kg. (a) What force (in N) must each engine exert backward on the track to accelerate the train at a rate of 4.00 ✕ 10−2 m/s2 if the force of friction is 7.50 ✕ 105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently, trains are very energy-efficient transportation systems. (Enter the magnitude.) b) What is the magnitude of the force (in N) in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines? (Assume both engines are at the front of the train.)
