A child goes down a playground slide with an acceleration of 1.26 m/s^2. Find out the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 35.0 below the horizontal.
The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space.
What is the maximum speed of the car (in km/hr) in the similar turn in the rain, when the coefficient of static friction is reduced to 0.720.
All through an experiment, a block of wood with a mass of 250 g is placed on an inclined plane. While the plane is raised to an angle of 43o, the block slides down the plane at a constant speed.
Determine the time it takes for the particle. A particle is traveling in a straight line at a constant speed of 28m/s. Suddenly, a constant force of 15.6N acts on it, bringing it to a stop in a distance of 66.8m.
A slab of marble is resting on the ground. It weighs 600 N and has the dimensions 0.1m x 0.2m x 1.0m. What is the greatest pressure that the slab can exert on ground.
An 80.7-kg jogger is heading due east at a speed of 1.950 m/s. A 53.60 kg jogger is heading 33.1° north of east at a speed of 2.89m/s. compute the magnitude (enter first) and direction of the sum of momenta of the two joggers.
Determine the normal force exerted by the road on the car, the normal force exerted by the car on the 73-kg driver, and the car speed at which the normal force on driver equals zero.
An automobile tire has a radius of 0.330 m, and its centre moves forward with a linear speed of v= 15.0 m/s. Find the angular speed of the wheel.
Suppose your weight has been constant, but then - after being introduced to really good chocolate - you start eating 100 extra food calories (recall, 1 food calorie is really 1kcal or 1000 calories of energy) every day without otherwise adjusting ..

Make a drawing of this situation, and choose the best axes for x and y so that you have the least number of components.)
Assume that you have two objects, one with a mass of 5 kg and the other with a mass of 17 kg, each with a charge of ?0.011 C and separated by a distance of 8 m. What is the electric force that these objects exert on one another? Answer in units of..
