Acceleration = v-u/t u = -1.31m/s v= 1.81 m/s t= 2.03
a= 1.81-(-1.31)/2.03= 3.12/2.03=1.53 m/s^2
average acceleration = 1.53 m/s^2

A busy chipmunk runs back and forth along a straight line of acorns that has been set out between its burrow and a nearby tree. At some instant, it moves with a velocity of -1.15 m/s. Then, 2.87 s later, it moves with a velocity of 1.73 m/s. What is the chipmunk's average accel eration during the 2.87 s time interval? average acceleration m/s2

1. In April 1974, Steve Prefontaine completed a 10 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 7.85 km mark at a time of 25.0 min If he accelerated for 60 s and then maintained his increased speed for the remainder of the race, calculate his acceleration over the 60 s interval. Assume his instantaneous speed at the 7.85 km mark was the same as his overall average speed up to that time....

Some chipmunks are running back and forth along a tree branch. One chipmunk is at rest at t = 0 s and starts running to the right. It speeds up to a speed of 1.5 m/s in 3 s. How far does it run in this time? Another chipmunk starts from rest and runs to the left. It speeds up to a speed of 2.1 m/s in 3.2 s. It then slows to a stop in...

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 5 sin πt + 2 cos πt, where t is measured in seconds. (Round your answers to two decimal places.) (a) Find the average velocity during each time period. (i) [1, 2] ? cm/s (ii) [1, 1.1] ? cm/s (iii) [1, 1.01] ?cm/s (iv) [1, 1.001] ?cm/s (b) Estimate the instantaneous velocity of the particle when...

Two soccer players kick a soccer ball back and forth along a straight line. The first player kicks the ball 15 m to the right to the second player. The second player kicks the ball to the left weakly; it only moves 3.5 m before stopping. (Consider the right to be the positive direction. Where applicable, indicate the direction with the sign of your answer.) (a) What is the total distance that the ball moved? m (b) At the end,...
