Overview
A car accelerates uniformly from rest to a speed of 25 m/s in 10 seconds. What is its acceleration?
A projectile is launched with an initial velocity of 20 m/s at an angle of 45° to the horizontal. Calculate the maximum height it reaches.
A 5 kg block is pushed with a force of 30 N on a frictionless surface. What is its acceleration?
A 10 Ω resistor and a 5 Ω resistor are connected in parallel to a 20V battery. What is the total current flowing in the circuit?
A light wave travels from air into water, where its speed decreases. How does this affect the wavelength and frequency of the wave?
