P.2) In this exercise you will see, from a different point of view, why the weight transfers toward the back when a car accelerates forward. If the car accelerates for- ward at 0.2g, then a force S must act, equal to 0.2mg. Imagine that the car, rather than riding on the ground, is traveling through space. In this case there are no positional constraints. We can ignore gravity since the car is in a zero g environment. Now imagine that a force S acts on the bottom of the tires, as shown, so that the center of mass feels an acceleration equal to 0.2gi. In the absence of gravity and the ground, calculate the response of the car, treating it as a single rigid body. What forces N1 and N2 must be exerted on the car to maintain zero rotational acceleration and zero vertical acceleration? How do these forces affect a car that's in contact with the ground? L - N1

Solving Problems with Newton’s Laws To sirmulate the apparent weightlessness of space orbit, astronauts are trained in the hold of a cargo aircraft that is accelerating downward at Why do they appear to be weightless, as measured by standing on a bathroom scale, in this accelerated frame of reference? Is there any difference between their apparent weightlessness on orbit and in the aircraft?
Suppose you can communicate with the inhabitants of a planet in another solar system. They tell you that on their planet, whose diameter and mass are 5.0103km and 3.61023kg , respectively, the record for the high jump is 2.0 m. Given that this record is close to 2.4 m on Earth, what would you conclude about your extraterrestrial friends’ jumping ability?
In an elevator problem, how do we know to use only the 2nd Newton law of motion for scale or elevator at rest?
In a later chapter, you will find that the weight of a particle varies with altitude such that w = mgr02/r2 where r0 is the radius of Earth and r is the distance from Earth’s center. If the particle is fired vertically with velocity v0 from Earth’s surface, determine its velocity as a function of position r. (Hint: use a dr = v dv, the rearrangement mentioned in the text.)
A rocket has an empty weight of 500 lb and carries 300 lb of fuel. If the fuel is burned at the rate of 1.5 lb/s and ejected with a velocity of 4400 ft/s relative to the rocket, determine the maximum speed attained by the rocket starting from rest. Neglect the effect of gravitation on the rocket.
Explain How to solve problems in which an object is falling freely under the influence of gravity alone?
Two masses are connected by a light string that passes over a frictionless pulley, as shown below. The masses are m1 = 6.00 kg, and m2 = 7.00 kg. If the coefficient of friction between the incline and m2 is 0.200 and the angle of the incline is 35.0°, find (a) acceleration of the two masses, (b) the tension in the string, and (c) the speed of each mass 2.00 s after being released from rest. Also, determine (d) what m2 would have to be in order to have the system accelerate in the direction opposite of what you found in (a). Assume m1 stays at 6.00 kg.
Why do we not put the net force of y equal to ma (mass x acceleration), since the object is accerlating the overall fnet cannot be equal to 0.
A space rocket of mass 1500kg travelled from the Earth to the Moon, whose centres are separated by 3.8 x 108 m. Calculate the magnitude and direction of the resultant force of gravity due to the Earth and Moon, on the space rocket, when it is midway between their centres.

Two masses are connected by a light string that passes over a frictionless pulley, as shown below. The masses are m1 = 6.32 kg, and m2 = 7.51 kg. If the coefficient of friction between the incline and m2 is 0.232 and the angle of the incline is 35.0°, find (a) acceleration of the two masses, (b) the tension in the string, and (c) the speed of each mass 2.11 s after being released from rest. (d) Also, determine what m2 would have to be in order to have the system accelerate in the direction opposite of what you found in (a). Assume m1 stays at the same. Note: this problem needs to be done using forces and FBDs - no credit will be given for doing it any other way.
In the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (~m1m2). While all scientific inferences must be experimentally verified, can you provide arguments as to why this must be correct?
