In a 400 m race, detailed video analysis indicated that a particular sprinter's speed can be modeled as a cubic function of time at the begining of the race, reaching a speed of 12.4 m/s in 2.1s, and as a linear function of time fo the remainder of the race . She crossed the finish lline traveling at 10.2m/s.? motion information

event1:    event:2    event3:

t1= t2=    t3=

r1= r2=    r3=

v1=    v2=    v3=

a1=    a2=    a3=

and I apologize is 2.1seconds not 12.1

A 5.00-kg bullet moving with an initial speed of Vi= 400 m/s is fired into and passes through a 1.00-kg block as shown in the Figure. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 1000 N/m. The block moves d = 5.00 cm to the right after impact before being brought to rest by the spring. Find: The speed at which the bullet emerges from the block. The kinetic energy...

A 880-kg race car can drive around an unbanked turn at a maximum speed of 44 m/s without slipping. The turn has a radius of 120 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 9800 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?
