A person is pushing a 8.58 kg block along a horiontal surface at a constant speed of 16.8 m/s. The person is applying a force of 8.05 N to the block at an angle of 35° above horizontal. If the block moves a distance of 3.5 m, what is the magnitude of the impulse parted upon the block by the person?

In a dance jump, the dancer lifts their center of mass 40 cm.  When they land, they bend their knees as they slow to a stop and their center of mass lowers by 7.0 cm in 50 ms.  The dancer’s mass is 60 kg. (a) What is the impulse on their body as they land? (b) What is the average force on the dancer’s body? {3360 N}

A pitcher throws a 0.200 kg ball so that its speed is 11.0 m/s and angle is 35.0° below the horizontal when a player bats the ball directly toward the pitcher with velocity 42.0 m/s at 30.0° above the horizontal. Assume +î to be along the line from the batter to the pitcher and +ĵ to be the upward vertical direction. (Express your answers in vector form.) (a) Determine the impulse (in N s) delivered to the ball. I = (b) If the force on the ball increases linearly for 4.00 ms, holds constant for 20.0 ms, and then decreases linearly to zero in another 4.00 ms, what is the maximum force (in N) on the ball? max N.S = N

A 1300 kg car moving at 6.3 m/s is initially traveling north in the positive y direction. After completing a 90° right-hand turn to the positive x direction in 3.6 s, the inattentive operator drives into a tree, which stops the car in 290 ms. What is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? What is the magnitude of the average force that acts on the car (c) during the turn and (d) during the collision? (e) What is the angle between the average force in (c) and the positive x direction? (a) Number i Units (b) Number i Units (c) Number i Units (d) Number i Units (e) Number i Units MacBook Pro esc > @ $ & 1 2 3 4 Q W E R Y tab S F K caps lock C V M hift fn control option command

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 72.9 x 105 kg, of which 14.7 x 10° kg is fuel. The rocket engine is then fired for 300 s, during which fuel is consumed at the rate of 360 kg/s. The speed of the exhaust products relative to the rocket is 3.82 km/s. (a) What is the rocket's thrust? After the 300 s firing, what are (b) the mass and (c) the speed of the rocket? (a) Number i Units (b) Number Units (c) Number i Units

In utter despair during this test, you kick the wall with force of 1250 N. Before rebounding, your foot is in contact with the wall for 5.95×10-3 s. What is the magnitude of the impulse you deliver to the wall?

A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 6.00 m/s in 0.814 s.   (a)What is the magnitude of the linear impulse experienced by a 76.0kg passenger in the car during the time the car accelerates?   (b)What is the magnitude of the average total force experienced by a 76.0kg passenger in the car during the time the car accelerates?

A force with a magnitude of 21 N is applied to an 7.1 kg object. How long would the force have to be applied in order to impart 56.6 kg m/s of impulse upon the object?
