Your task is to catch a 2.0 kg water balloon that is moving toward you at a velocity of 35 m/s. You have the options of catching the balloon over a period of 0.5 s or 1.5 s. Which method is the safest (driest) and why? Use the impulse-momentum approach to validate your answer.

A 0.05-kg toy car is initially moving at 1.4 m/s. Since the battery is losing power, the toy car has slowed down to 0.7 m/s. Calculate the impulse of the toy car. Input the numerical value only; do not include the units.

A 160 g ball is dropped from a height of 2.2 m, bounces on a hard floor, and rebounds to a height of 1.4 m. The figure(Figure 1) shows the impulse received from the floor.

The froghopper holds the title of the best jumper of the animal world. A 0.0198gram froghopper can accelerate at 4,000 m/s2 over 2.0 mm as it jumps. What is the impulse delivered to the froghopper as it makes this jump?

The bumper of a car has a force sensor mounted inside which records the force vs time graph during crash testing. A particular collision occurs between t = 0.075s and t = 2.32s and can be modelled by the following function: F(t) = 4t4 – 80t² + 140t – 10 A graph of the collision is also provided below: Impulse 60 50 40 30 20 10 1 time (s) Part A The impulse during the collision will be while the maximum force experience by the bumper will be 75 kg · m/s, 33N 54 kg · m/s, 54N O 75 kg · m/s, 54N 54 kg · m/s, 33N (N) aɔ10

A golf ball of mass 0.045 kg is hit off the tee at a speed of 35 m/s. The golf club was in contact with the ball for 3.50×10−3 s. Part A Find the impulse imparted to the golf ball. Express your answer to two significant figures and include the appropriate units. F¯Δt =________   Part B Find the average force exerted on the ball by the golf club. Express your answer to two significant figures and include the appropriate units. F=____________

Question 1 A 0.5 kg ball is thrown vertically upwards with an initial velocity of 10 m s¹¹. At its highest point, it momentarily stops before falling back down to the ground. Calculate the impulse experienced by the ball during the upward journey. ABCD 5 NS - 5 Ns ONS 10 N s

A professional golfer is examining a video of a practice swing. The high‑speed footage shows that his club is in contact with the ball (which was initially at rest on the tee) for only Δ?=0.771 ms, and the radar gun clocks the speed of the ball as ?b=176 mph after it comes off the club. The golf ball has a mass of ?b=45.9 g. a. What is the magnitude of the impulse imparted to the ball by the club? b. What is the magnitude of the average force of contact between the club and the ball?

Students in a technology class are racing cars propelled by carbon dioxide cartridges. A burst of gas is released when the seal of the cartridge is broken, and this propels the car down the track. The cartridges are designed to provide a certain impulse. Use the concepts of impulse and momentum to explain why such a cartridge will propel a lighter car to a higher speed.
