A sprinter with a mass of 88 kg accelerates uniformly from 0 m/s to 8 m/s in 3 s. (Assume the sprinter runs in the positive horizontal direction. Indicate the direction with the sign of your answer where appropriate.) How far does the sprinter go during the 3 s?

At t = 0.00 s a ball is started rolling up an inclined plane with an initial velocity of 6.00 m/s, 15.0°. At t = 2.00 s the ball reverses its direction and begins to roll back down. (a) How far up the slope does the ball travel? (b) Find the ball's acceleration. (c) Find the speed of the ball at t = 3.00 s. (d) Find the distance traveled by the ball during these 3.00 seconds. (e) Find the ball's position at t = 3.00 s.

A cat leaps to try to catch a bird. If the cat's jump was at an angle 59.73 degree above the horizontal and its initial velocity was 26.46 m/s. At what time (in seconds) does it reach the highest point of the jump? You should neglect air resistance and use g = 9.8 m/s2.

A graph of v(t) is shown for a world-class track sprinter in a 100-m race. (See figure below). Runner Velocity vs. Time Velocity (m/s) 14 12 2086 2 0 2 6 Time (s) 8 10 12 (a) What is his average velocity (in m/s) for the first 4 s? m/s (b) What is his instantaneous velocity (in m/s) at t = 6 s? m/s (c) What is his average acceleration (in m/s²) between 0 and 4 s? m/s² (d) What is his time (in s) for the race? S

A woman starts to swim directly across a 8.2-km-wide river. Her speed with respect to the water is 2.3 m/s. The river current carries the woman downstream at a speed of 0.91 m/s. (a)How much time, in seconds, does it take her to cross the river? __s b) How far downstream, in meters, will the river carry her by the time she reaches the other side of the river? __m

A football is kicked with an initial velocity of 9.1 m/s at an angle of 27.8°. If it hits the ground 1.5s later, how far does it travel? Answer: m

The kingda ka roller coaster in New Jersey is the world's tallest ride of it's kind. As the passenger cars are launched from rest at the start, they are accelerated uniformly to a speed of 57 m/s (128 mph) in just 3.5 s. ( assume the cars are launched in the positive horizontal direction . Indicate the direction with the sign of your answer where appropriate. a) what is the acceleration experienced by passengers on this ride in m/s ^2?  b) what is the acceleration experienced by passengers on this ride in g's?  c) if a certain passenger has a mass of 78kg what is the force in Newtons that acts on him during the launch phase of this ride? d) what is the force in pounds that acts on him during the launch phase of this ride?

A car is traveling east at 20 m/s. After 12 s its velocity is 14 m/s in the same direction. Find the magnitude and direction of the car's average acceleration. 0.50 m/s 2, west 0.30 m/s 2, east 0.30 m/s 2, west 0.50 m/s 2, east
