An electron starts from rest travels a distance of 15 cm with constant acceleration and hits a television screen at a speed of 3×10^6 m/s .Calculate the acceleration of the electron.

Answer 1

Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass of 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. What’s the acceleration of the wooden block when it hits the sensor?

Answer 2

1. V^2 = Vo^2 + 2a*d.
(3*10^6)^2 = 0 + 2a*0.15, a = ?.

2. F = M*a, a = F/M = 4.9/0.5 =
