Kathy Kool buys a sports car that can accelerate at the rate of 5.20 m/s2. She decides to test the car by racing with another speedster, Stan Speedy. Both start from rest, but experienced Stan leaves the starting line 1.00 s before Kathy. Stan moves with a constant acceleration of 3.80 m/s2, and Kathy maintains an acceleration of 5.20 m/s2.
(a) Find the time it takes Kathy to overtake Stan.
s
(b) Find the distance she travels before she catches him.
m
(c) Find the speeds of both cars at the instant she overtakes him.

If a metal wire carries a current of 23.0 mA, how long does it take for 12.0×1020 electrons to pass a given cross-sectional area anywhere along the wire? The magnitude of the charge on an electron is 1.6 × 10-19 C.
A radio station broadcasts at a frequency of 600,000 Hz. Know that radio waves have a speed of 3.00 x 10^8m/s, what is wavelength of these waves.
For tests using a ballistocardiograph, a patient lies on a horizontal platform that is supported on jets of air, that the patient and platform start from rest, determine the recoil velocity
When you push a 1.95kg book resting on a tabletop it takes 2.50N to start the book sliding. Once it is sliding, though, it takes only 1.50N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction betwe..
The hunter uses a small powerboat that moves at a maximum speed of 9 km/h with respect to the water. Illustrate what is the minimum time necessary for crossing?

A 3.00-m-long, 400 kg steel beam extends horizontally from the point where it has been bolted to framework of a new building under construction. A 74 kg construction worker stands at the far end of the beam.What is the magnitude of the torque abo..
Two cars cover the same distance in a straight line. Car A covers the distance at a constant velocity. Car B starts from rest and maintains a constant acceleration. Both cars cover a distance of 547m in 221s.
A 5kg steel ball strikes a wall with a speed of 8m/s at an angle of 60.0° with the surface. It bounces off with the similar speed and angle. If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ..
Now suppose that the two masses continue to move at the speed from Part A until they encounter a rough surface. The coefficient of friction between the masses and the surface is . If the blocks come to rest after a distance, which of following equ..
The tractor beam exerts a constant force of 4.0 104 N on the shuttlecraft. Both spacecraft are initially at rest. Explain how far does the starship move as it pulls the shuttlecraft aboard?
A 1650-kg car is travelling at 31.2 m/s. How fast must a 91.0-kg bicycle and rider be travelling to have the similar kinetic energy as the car.
