(i) the speed of the vehicle (in km/hr) at the instant the brakes are applied and The distance x meters traveled by a vehicle in time t seconds after the brakes are applied is given by To find acceleration we have to different the given equation two times Find the acceleration and kinetic energy at the end of 2 seconds. Since it reaches the ground the answer is having negative sign.Ī particle of unit mass moves so that displacement after t seconds is given by x = 3 cos (2t - 4). (iv) When the missile reaches the ground, the height of the missile = 0 By applying the value 4 for t, we get the distance covered by the missile. (iii) The missile is taking 4 seconds to reach its maximum height. So, the object is taking 4 seconds to reach the maximum height. (ii) When a object reaches its maximum height the velocity will become zero. The distance is changing with respect to time. Calculus broadly classified as Differentiation and Integration. (i) The time when the missile starts is 0. (iv) the velocity with which the missile strikes the ground. (ii) the time when the height of the missile is a maximum On such lines, movements in the forward direction considered to be in the positive direction and movements in the backward direction is considered to be in the negative direction.Ī missile fired ground level rises x meters vertically upwards in t seconds and x = 100t - (25/2)t 2. In such problems, it is customary to use either a horizontal or a vertical line with a designated origin to represent the line of motion. A few examples are population growth rates, production rates, water flow rates, velocity, and acceleration.Ī common use of rate of change is to describe the motion of an object moving in a straight line. The derivative can also be used to determine the rate of change of one variable with respect to another. ![]()
