A 4.0 N force acts for 3.0 s on an object. Theforce suddenly increases to 15 N and acts for one more second. What impulse was imparted by these forces to the object?
Please provide detailed explanation

A ball of mass 0.145kg is kicked by a soccer player. If the player's foot is in contact with the ball for 0.01sec and gives it a speed of 40m/sec, find theimpulse and average force on the ball during the kick.

Discuss the following in terms of impulse and momentum:
Why are padded dashboards safer in cars?
Why are nylon ropes, which stretch under stress, favored by mountainclimbers?
Why is it preferrred that railroad cars be loosely coupled with slack between cars?

A rubber ball of mass 0.05kg is dropped from a height of 10 cm above a table top. it bounces off the table and rises to the same height.
a. What is the shape of the graph of theforce exerted on the ball by the table as a function of time?
b. If the rubber ball was in contact with the table for 30ms, what is the avg force

In a slow-pitch softball game, a 0.200 kg softball crossed the plate at 20.00 m/s at an angle of 35.0° below the horizontal. The batter hits the ball toward center field, giving it a velocity of 40.0 m/s at 30.0° above the horizontal.
(a) Determine theimpulse delivered to the ball.
(b) If theforce on the ball increase

A 1.2 kg ball drops vertically onto a floor, hitting with a speed of 25 m/s. It rebounds with an initial speed of 10 m/s.
(a) What impulse acts on the ball during the contact?
(b) If the ball is in contact with the floor for 0.020 s, what is the magnitude of the average force on the floor from the ball?

Force of a Baseball Swing. A baseball has mass 0.145 kg.
1. If the velocity of a pitched ball has a magnitude of 45.0 m/s and the batted ball's velocity is 55.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball.
2. Find the magnitude of theimpulse applied to it by the bat.
3. If t

A ball of mass 1.5kg is thrown upward. it leaves the thrower's hand with a velocity of 10 m/s. Assuming the upward direction is positive:
a. how long does it take for the ball to return to the throwers hand
b.what is the ball's final velocity just before it reaches the hand?
c. what is the change in momentum of the ball?

Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0i-4.0j) m/s. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to (-380i+110j)N. What is the x-component of theimpulse of the net force applied to the ball? What is the y-componen
