Either all parts or none A uniform solid ball has a mass of 20 g and a radius of 5 cm. It rests on a horizontal surface. A sharp forceis applied to the ball in the horizontal direction 9 cm above the surface. The force rises linearly from 0 to apeak value of 40,000 N in s and then decreases linearly to 0 in another s. (The moment inertia for asolid ball is)a) What is the velocity of the ball after the impact?b) What is the angular velocity of the ball after the impact?c) What is the velocity of the ball when it begins to roll without sliding. (This means).d) For how long does the ball slide on the surface given the coefficient of kinetic friction

The Ministry of Trade and Industry has approached you to advice on the location of a pineapple processing factory in the Otia District under the 1D1F programme. Whereas some members of the ministry’s project committee want all pineapple-growing areas of the district to be considered fairly for the siting of the factory, others want the choice to be restricted to only the three major towns in the vicinity, namely, Nyamebekyere, Bodumase and Dedeiman. a) Given the information below, compute and graph the centre of gravity (in relation to the three major towns in the district) to enable those arguing for a fair district-wide consideration to visualize where the optimal location would be.
