A loaded truck rolls down a hilly road with a constant acceleration.The truck travels a distance of 1 km in 60 secs.What is its acceleration?Find the magnitude of net force acting on the truck if its mass is 7200 kg ? Please give correct answer

Answer»

your answergiven :initial velocity (u) = 0distance travelled (s) = 400 metertime TAKEN (t) = 20 secondsto FIND : ACCELERATION (a)solution :by using 2nd equation of motions = ut+1/2at²400 = 0*20+1/2*a*(20)²200a = 400A = 2 m/s²so, the acceleration of the rolling TRUCK will be 2 m/s².

(39.) A bus appears to go with a speed of 25 km/hr to a car driver, driving at the rate 7 km/hr northwards. If the busactually travels in east direction, its speed is -(A) 24 km/h(B) 23 km/h(C) 26 km/h(D) 30 km/h​

Answer»

24 km/ hrExplanation: Relative velocity of bus with respect to CAR ( Vbc) = 25 km/hr Velocity of car in north DIRECTION ( Vc) = 7 km/hr using vector law , Vbc^2 = Vb^2 + Vc^2 (25)^2 = (Vb)^2 + (7)^2 Vb = SQUARE root 576 so Vb = 24 km/hr

Differentiation and integration solving methods​

Answer»

This chapter explores some of the TECHNIQUES for finding more complicated integrals. (If you need to go back to basics, see the INTRODUCTION to Integration.)By STUDYING the techniques in this chapter, you will be able to solve a greater variety of applied calculus problems.Some of the techniques may look a BIT scary at first sight, but they are just the opposite of the basic differentiation formulas and transcendental differentiation formulas.Also, the methods in this chapter are based on the General Power Formula for Integration which we met before.Good luck!You may be interested to read the Introduction to Calculus, which has a brief history of calculus.
