Here are the solutions to the questions: 1. State the dimensions of the following physical quantities: a) acceleration Acceleration is the rate of change of velocity. Velocity has dimensions of length (L) divided by time (T). Dimension of velocity = LT = LT^-1 Acceleration is velocity divided by time. Dimension of acceleration = LT^-1T = LT^-2 b) pressure Pressure is force per unit area. Force has dimensions of mass (M) times acceleration (LT^-2). Dimension of force = M × LT^-2 = MLT^-2 Area has dimensions of length squared (L^2). Dimension of pressure = MLT^-2L^2 = ML^-1T^-2 c) density Density is mass per unit volume. Volume has dimensions of length cubed (L^3). Dimension of density = ML^3 = ML^-3 2. A projectile is launched with a velocity of 42 \, m/s at an angle of 30^ to the horizontal. If the time of flight is 4.2 \, s, calculate the maximum attainable height. |g = 10 \, m/s^2| Step
