When the car reaches point A, it has a speed of 25 m/s. After the brakes are applied, the speed is reduced by at = (0.001s - 1) m/s2 What is the magnitude of velocity of the car just before it reaches point C? What is the magnitude of acceleration of the car just before it reaches point C?

A snowboarder on a slope starts from rest and reaches a speed of 2.4 m/s after 7.1 s. (a) What is the magnitude (in m/s2) of the snowboarder's average acceleration? in m/s2 (b) How far (in m) does the snowboarder travel in this time? in m

In a test run, a certain car accelerates uniformly from zero to 16.8 m/s in 2.70 s. (a) What is the magnitude of the car's acceleration? m/s² (b) How long does it take the car to change its speed from 8.40 m/s to 16.8 m/s? S (c) will doubling the time always double the change in speed? O Yes O No Why?

An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 3.21 cm. If its x-coordinate 2.25 s later is −5.00 cm, what is its acceleration? cm/s2

A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.10 s for the ball to reach its maximum height. (a) Find the ball's initial velocity. m/s upward (b) Find the height it reaches. m

A car travels in a straight line along a road. Its distance x from a stop sign is given as a function of time t by the equation x(t)=at2-Bßt3, where a = 2.25 m/s² and B = 0.0550 m/s³. Calculate the average velocity of the car for the time interval to = 0 tot = 3.00 s . %D

An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 2.73 cm. If its x-coordinate 1.85 s later is −5.00 cm, what is its acceleration? cm/s2

Assume that an MX missile goes from rest to a suborbital velocity of 3.50 km/s in 90.0 s (the actual speed and time are classified). What is its average acceleration in m/s2? What is its average acceleration in multiples of g?

A snowboarder on a slope starts from rest and reaches a speed of 2.9 m/s after 8.7 s. (a) What is the magnitude (in m/s2) of the snowboarder's average acceleration?  m/s2 (b) How far (in m) does the snowboarder travel in this time?  m
