Solution: Using Newton's second law of motion: Force (F) = Mass(m)*Acceleration(a)
F = m.a
But, a = rate of change of velocity.
=> F = m(Vf - Vi)/Δt (Vi- initial velocity = 0 as the car and its rider was at rest)
=> F = (5.50*103) ( 50 - 0)/8
=> F = 34375 N. Answer
Thus, average net force = 34375 N.

90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...

On the ride "Spindletop" at an amusement Park, people stood against the inner wall of a hollow vertical cylinder with radius 2.5 m. The cylinder begins to turn, the rider, wall, and the floor moves in unison. When the cylinder reaches a constant speed of 7.2 m/s, the floor on which the rider is drops off. The rider does not fall with it but instead is pinned against the wall. (a) What is the minimum coefficient of static friction? (b)...

You are riding the new rollercoaster Fizzix Phun at your local amusement park. The technician with a mass of 100kg clears your car for 'takeoff'. The rollercoaster car full of people with a mass of 1000 kg is pulled up the initial hill by a lift device. The maintenance stairs up to the top of the hill consists of 11 flights of 30 stairs each wherein a single stair is 10cm high. The drop down the first hill is terrifyingly...
