Question 2 A lorry of mass 15 tonnes is travelling along a straight horizontal road. The lorry has a constant speed of 16 ms and the driving force being developed by its eng is 15625 N. There is a constant resistance to motion of R newtons. Model the lorry as a particle. (i) Find R. The lorry now ascends a hill which is inclined at 3° to the horizontal as shown in Fig. 3 below. The resistance to motion remains unchanged. 3⁰ Fig. 3 (ii) Draw a diagram showing the external forces acting on the lorry. When the lorry is accelerating at 0.1 ms 2 it has speed 10ms-¹ (iii) Find the power now being developed by the lorry's engine.

6. Please help me answer both parts to this physics problem

Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П. Identify Action Reaction Pairs A student in hot air balloon ascends vertically at a constant speed. Consider the four forces in this situation: Fl= the weight of the baloon F2= the weight of the student F3= the force of the student pulling on the earth F4= the support force of the…
