Suppose the speeder is traveling with a constant speed of 23m/s , and that the maximum acceleration of the police car is 3.5m/s^2 . If the police car is to start from rest and catch the speeder in 14s or less, what is the maximum head-start distance the speeder can have? Measure time from the moment the police car starts.
Establish angles subtended by the moon and the sun
What is acceleration of an object sliding down to plane
When in deep space, the block accelerates at 4.2 m/s^2 even as a 120 N force is applied to it. The coefficient of static friction for a particular plane and this block is 0.31. What angle can this plane make with horizontal before the object starts t..
Andy, age 16, lacks self-discipline, fails to plan ahead, and is rapidly frustrated by challenging tasks. He is nervous and overly critical of others. Make use of the psychoanalytic, humanistic and social-cognitive perspectives to give three contr..
A uniform magnetic field of 0.50 T is directed along the positive x axis. A proton moving with the speed of 60 km/s enters this field. The helical path followed by the proton shown has a pitch of 5.0 mm. find the angle between the magnetic field an..
Find out the x and y components of the force.
The average temperature in Gunnison for the first two months of the year are: 1) January (31 days) 10°F 2) February (28 days) 15° F. What are the total number of degree days for Gunnison over these two months?
A helicopter is ascending vertically with the speed of 5.79. At a height of 127 above the Earth, a package is dropped from a window. How long take the package to hit the ground.
The bullet becomes embedded in the block. if the coefficient of kinetic friction between the block and surface is .65 what was the speed of the bullet at once before impact.
Suppose a 63.00 kg boy and a 50.00 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.00 m/s2, find out the magnitude of the acceleration of the boy toward girl.
An aging coyote cannot run fast enough to catch a roadrunner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2. The coyote starts at rest 70.0 m from the edge of a cliff at the ins..
A 260-kg piano slides 4.2m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40.
