To test the performance of its tires, a car
travels along a perfectly flat (no banking) circular track of radius 151 m. The car increases
its speed at uniform rate of
at ≡
d |v|
dt = 2.51 m/s

until the tires start to skid.
If the tires start to skid when the car reaches
a speed of 25.9 m/s, what is the coefficient of
static friction between the tires and the road? The acceleration of gravity is 9.8 m/s

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)

A980-kg sports car collides into the rear end of a 2300-kg suv stopped at a red light. the bumpers lock, the brakes are locked, and the two cars skid forward 2.6m before stopping.the police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. what was that speed?
