A daredevil decides to jump a canyon. Its walls are equally high and 11 m apart. He takes off by driving a motorcycle up a short ramp sloped at an angle of 24°. What minimum speed must he have in order to clear the canyon?
A 1200kg car rounds a curve of radius 65 m banked at an angle of 14degrees. if the car is traveling at 30km/hr, will a friction force be required? if so, how much and in what direction.
In a women's 100-m race, accelerating uniformly, Laura takes 1.81 s and Healan 3.06 s to attain their maximum speeds, which they each maintain for the rest of the race.
What is the magnetic field strength. Consider a ladder 5 meters tall, and a 150 kg weight on top of it. The ladder is leaning against the wall.
A blue car of length 4.41 m is moving north on a roadway that intersects another perpendicular roadway (see figure below). The width of the intersection from near edge to far edge is 30.0 m.
An archer shoots an arrow horizontally at a target 12 m away. The arrow is aimed directly at the center of the target, but it hits 56 cm lower. What was the initial speed of the arrow.
If the ball is released from rest at a height of 0.91 above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? suppose the ball is a solid sphere of radius 3.7 and mass 0.14.
A car rounds a banked curve. The radius of curvature of the road is R .the banking angle is a. the coefficient static friction is f.
Assume that plane continues to fly with the similar velocity
A playground merry-go-round has a radius of 4.60 {rm m} and a moment of inertia of 250 kg m^2 and turns with negligible friction about the vertical axle through its center.
A horizontal vinyl record of mass 0.10kg and radius 0.10 m rotates freely about a vertical axis through its center with a rotational speed of 5.10 rad/s.
Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
