solution: final velocity:25m/s time :2s a=4m/s2 then, the formula we have v=u+at 25=u+4*2 25-8=u u=17m/s The displacement S=ut+1/2at2 S=17(2)+1/2(4)(2)(2) S=34+8 S=42m The displacement of the body is 42m
solution: u=10m/s a=a v=30m/s S=4km=4000m v2-u2=2as 900-100=2a*4000 800=8000a a=0.1m/s2 then, v=u +at 30=10+0.1*t 30-10=0.1t 20=0.1t t=200s The time taken is 200s.
solution: Given information, u=5m/s v=10m/s s=50m v2-u2=2as 100-25=2*a*s 75=2*a*50 75=100a a=0.75m/s2 The acceleration of the body is 0.75m/s2
Given information, u=10m/s v=20m/s t=2s v=u + at 20=10+2a 20-10=2a 10=2a a=5 m/s2 The acceleration of the body is 5m/s2
solution: just simple ,compare with v=u+at u=0.6m/s a=-0.3m/s2
solution: Given information: u =12m/s v=6m/s t=3s we have formula: v= u+ at a=v-u/t a=6-12/3 a=-2m/s2 by this answer, we can say the body is in decelarated motion.
The (a – b)^3 formula is used to find the cube of a binomial which is made up of the difference of two terms. It says (a – b)3 = a3 – 3a2b + 3ab2 – b3. This is one of the algebraic identities. This formula is used to calculate the cube of the difference between two terms …
Solution: Given information u=2m/s a=1m/s2 t=10sec We have the formula V=u+at V=2+1*10 V=12m/s.
Aside from India’s great performance by batters and bowlers, the fielding medal ceremony after each match has captured the attention of fans in the ongoing ICC World Cup 2023. India’s fielding coach T Dilip has been at the forefront of it, and his inventive methods of proclaiming the best fielder of the match have been …
