Two people fell down, one onto hard cement and one onto softer grass. Both people had a mass of 100 kg and were moving at 4 m/s as they fell. The person who hit the hard cement came to a complete stop very quickly, in .01 seconds. The person who fell onto the softer grass also came to a complete stop, but they did so more slowly, 0.5 seconds. What force did each of them experience when they came to a stop? Force on person who fell on cement Newtons Force on person who fell onto grass Newtons

reserve is the answer

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
