A flight attendant pulls her 70 N flight bag a distance of 247 m along a level airport floor at a constant speed. The force she exerts is 33.00 N at an angle of 52° above the horizontal.
A baseball is thrown at an angle of 27 degrees relative to the ground at a speed of 20.9m/s. The ball is caught 36.0231m from the thrower. The acceleration due to gravity is 9.81m/s square. Explain how long is it in the air ?
A high-speed flywheel in a motor is spinning at 450 when a power failure suddenly occurs. The flywheel has mass 38.0 and diameter 78 . The power is off for 25 and during this time the flywheel slows due to friction in its axle bearings.
You are driving home from school steadily at 94 km/h for 150 km. It then begins to rain and you slow to 63 km/h. You arrive home after driving 3 hours and 30 minutes. How far your hometown from school and what is was your average speed.
An object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x-direction when its x-coordinate is 3.18 cm. If its x-coordinate 2.95 s later is ?5.00 cm, what is its acceleration?
