9th class Physics problems 2.1, 2.2
- 1. Class 9th Physics Chapter#2, Kinematics Problem #2.1-2.2 By: Muhammad Zeeshan Easy learning
- 2. Given data: Velocity (V) = 36Km/h = πππππ ππππ = ππ π/π Time (T) = 10sec Find. Distance S=? Formula: S=VT S=(10)(10) π π Γ π S= 100m P#2.1. A train moves with a uniform velocity of 36Km/h for 10s. Find the distance traveled by it
- 3. Data: initial velocity Vi =0 Distance (S) = 1Km = 1000m Time t =100sec Find: Final velocity Vf=? Formula: Vf=Vi+at -------- (i) We need the value of βaβ so we first find it then put in this equation. For a, S=Vit +1/2 at2 β1000=0+1/2(a)(10000) a=π Γ ππππ πππππ = π. πm/s2 Now put values in eq. (i) Vf = 0+(0.2)(100) Vf = 20 m/s P#2.2. A train starts from rest. It moves through 1Km in 100s with uniform acceleration. What will be its speed at the end of 100s.
