Q1. With what speed should you toss a 130 ball straight up to hit the 15.0 -high roof of the gymnasium if you release the ball 1.10 above the ground? Solve this problem using energy.
Q2. A crate of 45.00 kg tools rests on a horizontal floor. You exert the gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 313 After that you must reduce your push to 208 N to keep it moving at a steady 25.0cm/s. A.) What is the coefficient of static and kinetic friction between the crate and the floor? B.) What push must you exert to give it an acceleration of 1.10 m/s^2? D.) Suppose you were performing the same experiment on this crate but were doing it on the moon instead, where the acceleration due to gravity is 1.62 m/s squared. What magnitude push would cause it to move? What will be its acceleration if you maintained the push in part b?
A luge and its rider, with a total mass of 83kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 44m/s. Assume that they stop with the constant deceleration of 2.9 m/s2.
A luge and its rider, with a total mass of 104 kg, emerges from a downhill track onto a horizontal straight track with the initial speed of 53 m/s. suppose they stop with the constant deceleration of 2.30 m/s2.
As part of the safety investigation, two 1400 {rm kg} cars travelling at 23 {rm m/s} are crashed into different barriers. Find the average forces exerted on (a) car that hits a line of water barrels and takes 1.7 {rm s} to stop, and (b) car that hits..
What is the speed of the projectile immediately before it hits the ground if air friction does one and a half times as much work on the projectile when it is going down as it did when it was going up.
A 33.2 m steel wire and a 25.6 m copper wire both with 1.00 mm diameters, are connected end to end and are stretched to a tension of 120 N. How long does it take the transverse wave to travel the entire length of the two wires.
While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0 degree banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and the road to keep t..
What is the ratio of the amplitude
A 3.60-{rm m}-long, 430 {rm kg} steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 66.0 {rm kg} construction worker stands at the far end of the beam. What is the magnitude..
A proton is initially at rest at a point where the potential is 459 V. Sometime later the proton is at a point where the potential is 218 V. If no force other than an electrostatic force acts on the proton, what is its final kinetic energy.
The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. Suppose that only static friction supplies the centripetal force, & find the radius r of the tyre.
