Question 7 Which of the following describe a conservative force? Your answer: O Atoy car stops moving suddenly as it hits a wall. O A person pushes a shopping cart and makes it start moving. O A spring is used to launch a ball vertically. Friction causes a plate sliding across a table to slow down and stop. Gravity makes a rock speed up as it falls.

Professional Application A car moving at 10 m/s crashes into a tree and stops in 0.26 s. Calculate the force the seat belt exerts on a passenger in the car to bring him to a halt. The mass of the passenger is 70 kg.
A crate having mass 50.0 kg falls horizontally off the back of the flatbed truck, which is traveling at 100 km/h. Find the value of the coefficient of kinetic friction between the road and crate if the crate slides 50 m on the road in coming to rest. The initial speed of the crate is the same as the truck, 100 km/h.
A cart is set rolling across a level table, at the same speed on every trial. If it runs into a patch of sand, the cart exerts on the sand an average horizontal force of 6 N and travels a distance of 6 cm through the sand as it comes to a stop. It instead the cart runs into a patch of gravel on which the can exerts an average horizontal force of 9 N, how far into the gravel will the cart roll before stopping? (a) 9 cm (b) 6 cm (c) 4 cm (d) 3 cm (e) none of those answers

A skier starts at rest at the top of a large hemisphericalhill (Fig. P7.63). Neglecting friction, show that the skier willleave the hill and become airborne at a distance h = R/3below the top of the hill. Hint: At this point, the normal forcegoes to zero.
A 0.19 kg hockey puck slides across an icy surface and experiences a small friction force of 0.09 N. If the puck is given an initial velocity of 4m / s how far does it slide before stopping? Your answer should be in units of m but you should only submit the number for your answer.
In a grocery store, you push a 12.3-kg shopping cart with aforce of 10.1 N. If the cart starts at rest, how far does it move in2.50 s? Graph and Explain.
A 10 kg object starts from rest and achieves a speed of 20 m/s in 10 s. How much force (in N) acted on the object?
Q2: Jane, who weighs 500 N, must cross a river full of hungry crocodiles to save Tarzan, who weighs 700 N, from danger. She jumps (from rest) off a cliff hanging from the end of an 18 m long vine, Fig.length, Fig. 1(b). From the top of the cliff to the lowest point of the trajectory she descends 3.0 m. The vine will breakif the force exerted on it exceeds 650 N.(a) Show that she will not be able to reach Tarzan?(b) And determine the angle of rupture θ, with respect to vertical.(c) Using a rope strong enough to hold them both, Jane rescues Tarzan. What will be the speed of thetwo when Jane "grabs" him (assume Jane is strong enough to hold him)?(d) Is the energy conserved? If yes, justify, if no, calculate∆K/Ki and explain what happened to the energy.

A 20-Mg train is traveling at a speed of 50 m/s. But the driver noticed that the bridge300-m ahead is missing. At once, he pulls the break, thus applying a frictionalresistance of Ff = 1000 N. At the same time Super Botting pushes back the train witha force of Fs = [(123)d + 100] N, where d is the distance that the train travels before stopping.Determine the stopping distance d, and mention whether or not Superbotting wouldbe able to save the train.
