Work done on the car and force-displacement graph.
Answer to Problem 17SSC
Work done on the car is
Explanation of Solution
Given:
Displacement is
Force is decreased at constant rate from 210 N to 40 N.
Formula Used:
Work done is given by area under the force-displacement graph.
Area of triangle is:
Calculation:
From the given condition the force-displacement graph will be,
As, work done is given by area under the force-displacement graph.
So, from the above graph, work done is

She is in the air for 1.04 s. A) With what initial velocity was Black Widow launched? 1 m = 3.28 ft B) What was Black Widow’s velocity just before she grabbed the speeder? Assume upwards is the positive direction.arrow_forward
- In Dark Souls 3 you can kill the Ancient Wyvern by dropping on its head from above it. Let’s say you jump off the ledge with an initial velocity of 3.86 mph and spend 1.72 s in the air before hitting the wyvern’s head. Assume the gravity is the same as that of Earth and upwards is the positive direction. Also, 1 mile = 1609 m. A) How high up is the the ledge you jumped from as measured from the wyvern’s head? B) What is your velocity when you hit the wyvern?arrow_forwardA) If Yoshi flings himself downwards at 9.76 miles per hour to hit an enemy 10.5 m below him, how fast is Yoshi traveling when he hits the enemy? 1 mile = 1609 marrow_forwardNo chatgpt pls will upvotearrow_forward
