ok this is the final question i have!!! a 0.080-kg egg test dummy is fitted with a helmet and attached to a swing. this egg test dummy is pulled back and released allowing it to collide with a cement block. the impulse on the egg test dummy is -0.39 N.s over an interval of 0.050 s. what is the magnitude of the force on the egg test dummy during this time interval? Step by Step please. thanks.

Thanks so much!!! I have another one thow!! A ball with a mass of 1.50 kg travelling +2.00 m/s collides with a stationary ball with a mass of 1.00 kg. After the collision the velocity of the 1.50-kg ball is +0.40 m/s. what is the velocity of the 1.00-kg ball after the collision? THanks

Thanks i got the awnser!!! A high performance car initially travelling 97.2 km/h came to a stop in just 2.9 s. The mass of the car and its contents was 1850 kg. what was the magnitude of the average net force on the car while it decelerated? Step by step please!!!

Thanks!! Another Question!! Based on a reaction time of 1.50 s and a braking rate of - 5.85 m/s the stopping distance of a vehicle initially travelling 90 km/h would be? Step by Step please!!

How would i figure out the acceleration?

How would i Figure out this question? A skydiver steps out of a helicopter hovering thousands of metres above ground. After 3.5 s of free fall the skydiver pulls the rip cord. What is the skydivers displacement during the 3.5 s of free fall? Please tell me step by step because i have tried everything to get this awnser and i cant get it thank you in advance!!

how do you convert km/h to m/s?

thanks for those equations but i already tried them before and i could not get the awnsers. so i just need the awnseres please.

1.To avoid a potential collision with wildlife crossing the road, the driver of a car travelling 105 Km/h fully applies the brakes to stop as quickly as possible. If the car stops 3.8 s after the brakes are applied, what is the braking distance? 2.A vehicle comes to a stop 10.0 s after the brakes are applied. While the brakes were applied, the vehicle travelled a distance of 75.0m. If the vehicles acceleration remained constant during the braking, what was the vehicles initial speed? 3.Based on a reaction time of 1.50 s and a braking rate of -5.85 m/s, the stopping distance of a vehicle travelling 90 Km/h would be? 4.A high performance car initially travelling 97.2 Km/h came to a stop in just 2.9 s. The mass of the car and its contents was 1850 kg. what was the magnitude of the average net force (braking force) on the car while it decelerated?
