Two particles, with identical positive charges and a separation of 2.70 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration A1 whose magnitude is 4.90 103 m/s2, while particle 2 has an acceleration A2 whose magnitude is 8.00 103 m/s2. Particle 1 has a mass of 5.55 10-6 kg. (a) Find the charge on each particle. q1= C? q2= C? (b) Find the mass of particle 2. kg?
A rail car that weighs 34 N is accelerated at 8.3 m/s/s for 5.9 seconds. How much work is done on the rail car? The acceleration is constant
A car is travelling at 24 m/s while the driver spots a large pothole in the road a distance 35 m ahead. She immediately applies her brakes. If her acceleration is -4.30m/s2, does she manage to stop before reaching pothole? What is the stopping dis..
