I’m struggling with question 3 hell would be greatly appreciated ? 2. v 20.0 m/s 53.1° a) b) What is the x component of v? What is the y component of v? 3. The distance from centre field to home plate is 105 m. Assuming that the ball is thrown at an inclination of 45o with the horizontal, with what speed must the ball leave the fielder's hand if it is to reach home plate at the same height at...
I need some help with question 3 using 1D kinematic equations (I couldn’t understand the more complex version from the last question I asked) iv) (iii) 2. , V 20.0 m/s 53.1° a) b) What is the x component of v? What is the y component of v? 3. The distance from centre field to home plate is 105 m. Assuming that the ball is thrown at an inclination of 45° with the horizontal, with what speed must the ball...
4. An object travels 40.0 m east at a constant speed of 10.0 m/s. The object then travels 30.0° east of north, starting at 10.0 m/s but undergoing a constant acceleration to a final speed of 20.0 m/s over a period of 10.0 seconds. What is its total displacement?
A ball thrown horizontally with speed vi = 20.0 m/s travels a horizontal distance of d = 58.0 m before hitting the ground. From what height h was the ball thrown? When setting up projectile motion questions, which of the following characteristics of projectile motion are important to keep in mind? Check all that apply. a. Projectile motion is the motion of an object that moves in two dimensions under the influence of gravity and air resistance. b. Although the...
Question 25 1 pts A 3kg object traveling at 4 m/s is pushed by a net force of 5 N. The speed increases to 6 m/s. Find the distance the object travels. O 0.4m O 1.2 m 4.8m 06m O None of the above Question 26 1 pts A 40.0 N crate is pulled up a 5.0 m inclined plane. The angle of inclination of the plane to horizontal is 37º. If there is a constant force of friction of...
2. General Motion with Unit Vectors and Components An object undergoes the following consecutive displacements: s (2i +3j +5k)m,s2 (6i-91+ 2krn, and s,-(10i + 8j-km a) Find the resultant displacement in terms of unit vectors and components. b) State the magnitude of the resultant displacement. 2. Suppose a hiker travels 5 km southwest from their camp. Then, the hiker travels 2 km 75° north of east. a) Find the displacement of the hiker form their camp. b) If the hiker...
2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
please help and answer all ASAP please thank you so much Question 49 (1 point) When light travelling in glass enters glass with a higher index of refraction, the wave will be: a) partially transmitted with a change in phase b) transmitted forming a standing wave pattern in air c) reflected so as to form a node at the junction d) totally reflected at the junction e) partially reflected without a change in phase Question 38 (1 point) The charge,...
