Motion In A Straight Line Mock Tests

A ball is thrown vertically upward with initial velocity 20 m/s. The maximum height reached is: (g = 10 m/s²)

In an elastic collision between two bodies:

When a body is projected vertically upward, the maximum height is reached when:

A body moves along a straight line such that its position x (in metres) at time t (in seconds) is given by x = 2t³ − 6t² + 12t + 6. At what time t is the acceleration of the body zero?

A ball is thrown vertically upward with an initial velocity of 20 m/s. Taking g = 10 m/s², the time taken by the ball to return to the point of projection is: (Take upward direction as positive)

A particle moves along a straight line such that its position at time t is given by x(t) = 6t² - 2t³ meters. The velocity of the particle at the instant when its acceleration is zero is:

A car travels from point A to point B, a distance of 120 km, at a constant speed of 60 km/h. It returns from B to A along the same path at a constant speed of 40 km/h. What is the average speed of the car for the entire round trip?

Rain is falling vertically downward with a speed of 35 m/s. Wind begins blowing after some time with a speed of 12 m/s toward the east. A woman riding a bicycle eastward with a speed of 12 m/s should hold her umbrella in which direction to protect herself from the rain?
