Explanation Formula used: s = u t + 1 2 a t 2 Where, s = distance u = initial velocity t = time taken a = acceleration v 2 = u 2 + 2 a s Where, v =final velocity s = distance u = initial velocity a = acceleration Given: The time required to solidify the ball bearing= 4 s Calculation: To calculate the height of the tower, use the formula s = u t + 1 2 a t 2 . The initial velocity of the bearing is zero, so the formula becomes s = 1 2 a t 2 . The acceleration will be acceleration due to gravity, i.e., 9.8 m/s 2 . s = 1 2 × 9

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, fo…

4.35 ⚫ Two adults and a child want to push a wheeled cart in the direc- tion marked x in Fig. P4.35 (next page). The two adults push with hori- zontal forces F and F as shown. (a) Find the magnitude and direction of the smallest force that the child should exert. Ignore the effects of friction. (b) If the child exerts the minimum force found in part (a), the cart ac- celerates at 2.0 m/s² in the +x-direction. What is the weight of the cart? Figure P4.35 F₁ = 100 N 60° 30° F2 = 140 N

4.21 ⚫ BIO World-class sprinters can accelerate out of the starting blocks with an acceleration that is nearly horizontal and has magnitude 15 m/s². How much horizontal force must a 55 kg sprinter exert on the starting blocks to produce this acceleration? Which object exerts the force that propels the sprinter: the blocks or the sprinter herself?
