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?
What is the magnitude
A uniform shaft, fixed at one end & free at other, is twisted so that each cross - section rotates through an angle proportional to the distance from the fixed end. If the shaft is released from rest in this position, determine the s
Two horizontal forces, 249 N and 165 N, are exerted in opposite directions on a crate. What is the net horizontal force on the create? Be sure to point to the direction of the net force.
A ranger in a national park is driving at 59 km/h while a deer jumps onto the road 61 m ahead of the vehicle. After a reaction time of t s, ranger applies the brakes to produce an acceleration of -3 m/s2. What is the maximum reaction time allowed if ..
At the factory, a noon whistle is sounding with the frequency of 464 Hz. As a car travelling at 76 km/h approaches the factory, driver hears the whistle at frequency fi. After driving past the factory, the driver hears frequency ff. What is the chang..
At rest when constructed, the ring is set rotating about its axis so that the people inside experience effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the r..
