A typical male sprinter can maintain his maximum accelerationfor 2.0 s, and his maximum speed is 10 m/ s. After he reachesthis maximum speed, his acceleration becomes zero, and then he runs atconstant speed. Assume that his acceleration is constant during the first 2.0 s of the race, that he starts from rest, and that he runs in a straightline. What is the magnitude of his average velocity for a race of these lengths: (i) 50.0 m; (ii) 100.0 m; (iii) 200.0 m?

- (6) Water striders are insect that propel themselves on the surface of ponds by creating vortices in the water shed by their driving legs. The velocity-versus-time graph of 2 a 17 mm long water strider that moved in a straight line was created from a video. See the figure attached. The insect started from rest, sped up by taking two strides, and then slowed down until it stopped. Estimate (a) maximum speed (in m/s), (b) the maximum acceleration (in m/s2 ) (c) the total displacement (in m) of the water strider. Note that the velocity on the graph in the textbook is given in units of length of water strider body per second.arrow_forward(I) A particle at is at and at t1=-2.0 s is at x1=4.8cm and at t2=4.5 s is at x2 = 8.5 cm.

When t 2 s, v = -15 m/s, and when t 10s., v 0.36 m/s. Knowing that the particle is twice as far from the origin when t 2s as it is when t 10 s, determine (a) the position of the particle when t 2 s and when t = 10 s, (b) the total distance traveled by the particle from t 2 s to tt = 10 s.arrow_forwardThe acceleration of a particle is defined by the relation a= -k/v, where k is a constant.

It then turns abruptly and gallops halfway back in 1.8 s. Calculate (a) its average speed and (b) its average velocity for the entire trip, using “away from the trainer" as the positive direction.arrow_forwardIn the design of a rapid transit system, it is necessary to balance the average speed of a train against the distance between station stops. The more stops there are, the slower the train’s average speed. To get an idea of this problem, calculate the time it takes a train to make a 15.0-km tripin two situations: (a) the stations at which the trains must stop are 3.0 km apart (a total of 6 stations, including those at the ends); and (b) the stations are 5.0 km apart (4 stationstotal). Assume that at each station the train accelerates at a rate of 1.1 m/s2until it reaches 95 km/h then stays atthis speed until its brakes are applied for arrival at the next station, at which time it decelerates at - 2.0 m/s2 Assume it stops at each intermediate station for 22 s.arrow_forward
