Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

Two average forces. A steady stream of 0.234 kg snowballs is shot perpendicularly into a wall at a
speed of 4.70 m/s. Each ball sticks to the wall. The figure gives the magnitude F of the force on the
wall as a function of time t for two of the snowball impacts. Impacts occur with a repetition time
interval At₁ = 48.0 ms, last a duration time interval Ata = 11.0 ms, and produce isosceles triangles on
the graph, with each impact reaching a force maximum Fmax = 200 N. During each impact, what are
the magnitudes of (a) the impulse and (b) the average force on the wall? (c) During a time interval of
many impacts, what is the magnitude of the average force on the wall?

From what might be a possible scene in the comic book The X-Men, the Juggernaut (mJ) is charging into Colossus (mC) and the two collide. The initial speed of the Juggernaut is vJi and the initial speed of Colossus is vCi. After the collision, the final speed of the Juggernaut is vJf and the final speed of Colossus is vCf as they each bounce off of the other, heading in opposite directions. a. What is the impulse experienced by the Juggernaut? b. What is the impulse experienced by Colossus? c. In your own words, explain how these impulses must compare with each other and how they are related to the average force each superhero experiences during the collision.
To lift off from the Moon, a 9.50 105 kg rocket needs a thrust larger than the force of gravity. If the exhaust velocity is 4.25 103 m/s, at what rate does the exhaust need to be expelled to provide sufficient thrust? The acceleration due to gravity on the Moon is 1.62 m/s2.
The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms.(This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73 m/s. Suppose that the positive direction of the x-axis is along the direction of motion of the ball after Big Bill's hit. What is the x-component of the force exerted by Big Bill on the tennis ball in his record serve? If Big Bill's opponent returned his serve with a speed of 55 m/s what is the x-component of the force he exerted on the ball, assuming only horizontal motion?

A ball moving at 0.95 m/s collides with a stationary ball. After a collision, they separated with the first ball moving 50° to the right while the other ball moved 40° to the left. If both balls has a mass of 1.5 kg, compute for their final velocities.
During a violent thunderstorm, hail of diameter 0.59 cm falls directly downward at a speed of 30 m/s. There are estimated to be 130 hailstones per cubic meter of air. (a) What is the mass (in g) of each hailstone (density = 0.92 g/cm3)? (b) Assuming that the hail does not bounce, find the magnitude of the average force on a flat roof measuring 12 m x 19 m due to the impact of the hail. (Hint: During impact, the force on a hailstone from the roof is approximately equal to the net force on the hailstone, because the gravitational force on it is small.)

Airplane flight recorders must be able to survive catastrophic crashes. Therefore, they are typically encased in crash-resistant steel or titanium boxes that are subjected to rigorous testing. One of the tests is an impact shock test, in which the box must survive being thrown at high speeds against a barrier.

What is the magnitude of the average net force that acts on the box during the collision?
