Question

Starting from rest, a 69.0 kg woman jumps down to the floor from a height of 0.800 m, and immediately jumps back up into the air. While
she is in contact with the ground during the time interval 0<t< 0.800 s, the force she exerts on the floor can be modeled using the
function
F= 9,200t - 11,500r?
where F is in newtons and t is in seconds.
(a) What impulse (in N. s) did the woman receive from the floor? (Enter the magnitude. Round your answer to at least three significant
figures.)
N.S
(b) With what speed (in m/s) did she reach the floor? (Round your answer to at least three significant figures.)
m/s
(c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.)
m/s
(d) To what height (in m) did she jump upon leaving the floor?

On a test flight a rocket with mass 400 kg blasts off from the surface of the earth. The rocket engines apply a constant upward force F until the rocket reaches a height of 100 m and then they shut off. A) If the rocket is to reach a maximum height of 400 mm above the surface of the earth, what value of F is required? Assume the change in the rocket's mass is negligible. (Express your answer with the appropriate units.)
Starting from rest, a 64.0 kg woman jumps down to the floor from a height of 0.800 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds. (c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) (d) To what height (in m) did she jump upon leaving the floor?
A car moving at 14 m/s crashes into a tree and stops in 0.91 s. The mass of the passenger inside is 69 kg. Calculate the magnitude of the average force, in newtons, that the seat belt exerts on the passenger in the car to bring him to a halt.
A 3.0-kg block (A) is attached to a 1.0-kg block (B) by a massless spring that is compressed and locked in place, as shown in the figure. The blocks slide without friction along the x-direction at an initial constant speed of v = 2.0 m/s. At Lee A A 000 B ell time to 0 s, the positions of blocks A and B are %3D 1.2 m, respectively, at which point a mechanism releases the spring, and the blocks begin to XA.i = 1.0 m and xB.i = XB.r oscillate as they slide. If 2.0 s later block B is located at xB.f = 7.5 m, what will be the position xA.f %3D of block A? XA,f
(a) Find the speed at which Superman (mass=90.0 kg) must fly into a train (mass = 17485 kg) traveling at 65.0 km/hr to stop it. Running into the train at that speed would severely damage both train and passengers. (b) Calculate the minimum time Superman must take to stop the train if the passengers experience an average horizontal force of 0.410 their own weight. (c) How far does the train then travel while being slowed to a stop?
-30 At the instant the displacement of a 2.00 kg object relative to the origin is d = (2.00 m)i + (4.00 m)j – (3.00 m)k, its veloc- ity is v = -(6.00 m/s)i + (3.00 m/s)j + (3.00 m/s)k and it is sub- ject to a force F= (6.00 N)i -(8.00 N)j + (4.00 N)k. Find (a) the acceleration of the object, (b) the angular momentum of the object about the origin, (c) the torque about the origin acting on the ob- ject, and (d) the angle between the velocity of the object and the force acting on the object.
Your car (1153 kg) dies & you need to get it out of a parking spot. You & your friends apply 6959 N [R 16O D] for 10 seconds. It then starts to move on its own. If the coefficient of friction is 0.31, how far will it travel in total?
In the figure, a runaway truck with failed brakes is moving downgrade at 109 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of 0 = 17°. The truck's mass is 1.3 x 104 kg. (a) What minimum length Lmust the ramp have if the truck is to stop (momentarily) along it? (Assume the truck is a particle, and justify that assumption.) Does the minimum length Lincrease, decrease, or remain the same if (b) the truck's mass is decreased and (c) its speed is decreased? (a) Number i Units (b) (c)
A toy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane.
