About 80 g of blood is pumped from the heart during each heartbeat. The blood starts at rest and has a speed of about 0.60 m/s in the aorta. If the pumping takes 0.17 s, What is the magnitude of the average force on the blood?
A car of mass 1.2 103 kg is traveling east at a speed of 24 m/s along a horizontal roadway. When its brakes are applied, the car stops in 5.3 s. What is the average horizontal force exerted on the car while it is braking?
A duck has a mass of 2.10 kg. As the duck paddles, a force of 0.140 N acts on it in a direction due east. In addition, the current of the
water exerts a force of 0.180 N in a direction of 57.0° south of east. When these forces begin to act, the velocity of the duck
is 0.100 m/s in a direction due east. Find (a) the magnitude and (b) the direction (relative to due east) of the displacement that the duck
undergoes in 3.80 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)

- A box of mass 10.2 kg is slid along the floor. The initial speed of the box is 2.5 m/s and it comes to rest after 8.1 m. What was the magnitude of the force of friction acting on the box during this motion? You must enter you answer and include the SI units. (For example: 3.0kg)arrow_forwardA railroad car which has a mass 9216 kg is constrained to move along a horizontal track under the action of a wind blowing in the direction of the track. The frictional resistance to the car motion is 1/200 of its weight. The force exerted by wind is P=kSu2, where S is the area of the backside of the railroad car, equals to 6 m2, and u is the velocity of the wind relative to car, k=0.12. The absolute velocity of the wind is w=12 m/s. The initial velocity of the railroad car is 0. Determine:a) the maximum velocity vmax of the railroad car;b) the time T taken to reach this velocity;c) the distance x, travelled by the railroad car before reaching a velocity of 3 m/sarrow_forwardTwo students are pushing crates across a frictionless floor. The crates are initially at rest. Bing applies a horizontal force of 13 N to his crate. Bob, who is taller than Bing, pushes on his crate at an angle of 53 degrees below the horizontal, also with a force of 13 N. Find the ratio of the masses of the two crates if Bing's crate is moving at twice the speed of Bob's crate after they have traveled a distance of 23.5 m across the floor?arrow_forward
