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?”

Activity 2. A hunter observed a bird flying overhead and estimated the height at 15m and its speed at 20 m/s. His rifle is capable of a muzzle velocity of 48 m/s. If he fires at the instant the bird is directly overhead, at what angle should he incline his rifle in order to hit it? How many meters from his position will the bird hit the ground assuming that the weight of the bullet compared to the weight of the bird is negligible? (Ans. 0= 65.39°, d=42.20m) 20m/s 48m's d=?

She launches herself from the ground with an initial velocity of 29.4 m/s at an angle 59 degrees above the horizontal, but instead of landing on the roof she hits the wall of the building. launching at a speed of 47.0 m/s. She goes over the building entirely and lands on the ground on the other side.How much time does she spend in the air? What is the height of the action hero at the peak of her trajectory? How far from her launch point will she land?

Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 22 m/s at an angle θ = 28° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position. A) Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. B) At what horizontal distance d from the building base, where should the fireman place the hose for the water to reach its maximum height as it strikes the building? Express this distance, d, in terms of v0, θ, and g.

Enter an expression in terms of v0, theta, and g for the time it takes the ball to travel to its maximum veertical height.

An industrious chipmunk creates an acorn catapult. This acorn catapult fires a 0.00543 kg acorn at an initial speed of 21.8 m/s. The catapult can be moved to any horizontal distance from the target and it can be set to shoot the acorn at any angle between 14° and 86.6°. The chipmunk will adjust the distance and angle until he gets a shot just right, and he deems a shot to be successful when the target is hit at the moment the acorn reaches its apex d) If the acorn hits the target and bounces back, losing 24.2% of its speed in the collision, what is the magnitude of the change in the acorn's momentum from immediately before the collision to immediately after the collision? e) If the duration of the collision described in part D is 3.01 x 10^-5 s, what is the magnitude of the average force the acorn imparts onto the target?
A boy is playing flying fox over a swimming pool as illustrated in the figure. A cable mounted on the top of a tall tower runs down to the ground with an angle = 26° with respect to the horizontal. The boy at the top of the tower grabs a pulley on the cable and slides down from rest. His initial height was ho 15 m above the water. When he reaches hi above the water, he releases his hands from the pulley and falls into the water. The boy is subject to the regular force of gravity (g-9.80665 m/s2). Ignore friction and air resistance. <=10m (a) Determine the speed of the boy at the moment he releases his hands from the pulley. Answer: 9.90 m/s (b) Determine the speed of the boy at the moment he splashes into the water. Answer: 17 (c) At what angle with respect to the horizontal does the boy enter the water? Answer: 57.85 degrees
