Answer:
The speed of the car is 44 m/s
Explanation:
Given:
Mass of car = 1000 kg
K.E = 968000 J
To Find:
Speed of car = ?
Now, We know the formula to find K.E
K.E = 0.5 × mv²
where,
m = mass
v = velocity/speed
So,
K.E = 0.5 × mv²
968000 = 0.5 × 1000 × v²
Now, make v² subject
v² = 968000 ÷ 0.5 × 1000
v² = 968000 ÷ 500
v² = 1936
√v² = √1936
v = 44 m/s
Thus, The speed of the car is 44 m/s
For Verification Only:-
K.E = 0.5 × mv²
968000 = 0.5 × 1000 × 1936
968000 = 968000
L.H.S = R.H.S
Hence Proved!
