A small, 300 g cart is moving at 1.10 m/s on an air track when it collides with a larger, 4.00 kg cart at rest. After the collision, the small cart recoils at 0.890 m/s. What is the speed of the large cart after the collision (answer in m/s please)?
Avoiding air resistance, what is the magnitude of the total velocity of the package at the moment it is thrown as seen by an observer on the ground? Answer in units of m/s.
The model airplane in figure below is flying at a speed of 19 m/s on a horizontal circle of radius 17 m, What is the net work done on the plane
Monochromatic light (640 nm) strikes a pair of slits at normal incidence, forming the double-slit interference pattern on a screen located 1.82m from the slits. It shows the interference pattern observed on the screen. What is the slit separation.
Suppose a car is traveling at 14 m/s, and the driver sees a traffic light turn red. After 0.50 s has elapsed (the reaction time) the driver applies the brakes and the car decelerates at 8.0 m/s2.
A 52.5 g Super Ball travelling at 30 m/s bounces off a brick wall and rebounds at 16.0 m/s. A high-speed camera records this event. If the ball is in contact with wall for 3.25 ms, what is the magnitude of the average acceleration of ball during t..
Determine an angle (in radians) through which the drill rotates during this period.
A box with a mass of 8 kg is lifted (without acceleration) through a height of 9 m, in order to place it upon the shelf of the closet.
Two particles of masses m and 3.00m are moving toward each other along the x-axis with the same speed v. They undergo a head on elastic collision and rebound along the x- axis. Find out the final speed of the heavier object.
A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
