Moderate -0.8 This is a straightforward SUVAT application with vertical motion under gravity. Students need only apply standard equations (v = u + at for time to peak, then double it; s = ut + ½at² for height) with no problem-solving insight required. It's slightly easier than average due to being a direct two-step calculation with clearly stated conditions.
1 A particle is thrown vertically upwards and returns to its point of projection after 6 seconds. Air resistance is negligible.
Calculate the speed of projection of the particle and also the maximum height it reaches.
