(a) To determine The vector equation for path of baseball. Explanation From Example 5, the initial velocity is υ 0 = 152 ft/sec , the launch angle is α = 20 ° . Also a component of − 8.8 i ft/sec is added to the initial velocity and assume a drag coefficient k = 0.12 . Then using the linear drag from Exercise 41, obtain the distance downrange as follows. x = υ 0 k ( 1 − e − k t ) cos α = 152 0.12 ( 1 − e − 0.12 t ) cos 20 ° Obtain the height of the projectile as shown below. y = 3 + υ 0 k ( 1 − e − k t ) ( sin α ) + g k 2 ( 1 − k t − e − k t ) = 3 + 152 0.12 ( 1 − e − 0.12 t ) ( sin 20 ° ) + 32 ( 0.12 ) 2 ( 1 − 0.12 t − e − 0.12 t ) Obtain the vector equation for path of the baseball as follows. r = x i + y j = { ( 152 0.12 ( 1 − e − 0 (b) To determine The maximum height reached by baseball and the time it reaches the maximum height. (c) To determine The flight time and range of the baseball. (d) To determine The time when the baseball is at 30 ft height and the distance downrange at that height. (e) To determine To explain: Whether the batter hit a home run or not.

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…
