A car covers first 2 km of the distance of 4 km with speed of 30 km/h and the remaining distance of 2 km with a speed of 20 km/h . The average speed of the car is

24 km/h

25 km/h

50 km/h

26 km/h

A vehicle travels half the distance L with speed u and the other half with speed V then its average speed is

$\frac{\left(u+v\right)}{2}$

$\frac{\left(2u\ +v\right)}{u\ +v}$

$\frac{2uv}{u+v}$

$\frac{L\left(u+v\right)}{uv}$

A spring with one end attached to a mass and the other to a rigid support is stretched and released.

Magnitude of acceleration, when just released is maximum.

Magnitude of acceleration, when at equilibrium position, is

maximum.

Speed is maximum when mass is at equilibrium position.

Magnitude of displacement is always maximum whenever speed is minimum.

A body is thrown upward and after some time the body reaches it’s maximum height, At maximum height:

It’s velocity and acceleration both are zero.

It’s velocity is zero and acceleration is maximum

It’s velocity is maximum and acceleration is minimum

It’s velocity is zero and acceleration is equal to acceleration due to gravity(g).

1:2

1:√3

√3:1

1:3
