- How much force would a car’s tires need to provide to accelerate an 1800 kg car at a rate of 4.0 m/s2?A 60.8 kg person is standing inside an elevator. The elevator is moving upward at 3.49 m/s and is decreasing speed at a rate of 1.25 m/s^2. What is the force of gravity that is acting on the person?A mass of 17 kg is linked to a rope. the rope is pulled upward causing the mass to accelerate at 3.3 m/s^2, close to the surface of the earth. What is the tension in the rope in Newtons. Use g=10 m/s^2
- A 71.2 kg high jumper leaves the ground with a vertical velocity of 5.9 m/s. How high can he jump? The acceleration of gravity is 9.8 m/s^2 answer in units of m220. 5 N of force is required to get a 75 kg shopping cart rolling. How much force will you have to apply to the same shopping cart after it starts moving to get it to accelerate at 5.0 m/s2 µs=0.42 and µk=0.30A person stands on a scale inside an elevator at rest. The scale reads 800 N. The elevator accelerates downward at the rate of 2.4 m/s ^ 2 . What does the scale read then? Calculate answer to one decimal. (use g = 9.8 m/s ^ 2 )
- A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the oor of the elevator. You may take g = 10 N/kg. While it is accelerating downwards hat does the scale read (in newtonsIf you are floating in outer space, and you need to change your motion in order to get back to the safety of your spaceship. You throw your shoe away with a force of 320 Newtons, which means the shoe pushes back on you with a force of 320 Newtons. If you have a mass of 61 kg, what is the magnitude of your acceleration?A 80 kg woman on roller skates pushes a 30 kg girl, also on roller skates, with a force of 100 N. The magnitude of the force exerted by the girl on the woman is O 200 N O 100 N O 50 N O 40 N O 38 N zero
- 0 cm 10.0 cm 35.0 N 45.0 cm xcm 30.0 N 3. What is the value of the force at 40.0 cm in the diagram below? 0 cm 40.0 cm 25.0 N (x) N 50.0 cm 100.cm 30.0 NA "doomsday" asteroid with a mass of 1.0 × 1010 kg is hurtling through space. Unless the asteroid's speed is changed by about 0.25 cm/s, it will collide with Earth and cause tremendous damage. Researchers suggest that a small "space tug" sent to the asteroid's surface could exert a gentle constant force of 2.4 N . For how long must this force act?
