. Before hitting the ground ,the velocity v is given by v

a. C

b. D

c. E

d. B

. The instantaneous velocity is given by the slope of the displacement time graph.

Since slope is negative at point B, instantaneous velocity is negative at B

Hence (d) is correct

a. 60m

b. 40m

c. 50m

d. 30m

. Acceleration is given by the slope of the velocity time graph

Non zero acceleration happened in the time interval 20 to 40 sec as the slope of the graph is non zero in that time interval

Now displacement in that interval is given by the area enclosed the v-t curve during that interval

So area=(1/2)20*3 +20*1=50m

Hence (c) is correct

a. It first increases and then decreases

b. It is a non zero constant

c. it is zero

d. none of the above

. The instantaneous velocity is given by the slope of the displacement time graph.

As slope of both the particle displacement time graph is constant.That means there individual velocities are constant.

So relative velocity is also constants

so it is a non zero constant as they have different velocity

Hence (b) is correct

A Jeep starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110m. Determine the acceleration of the Jeep.

John is riding the Giant Drop at Canada. If John free falls for 2.6 seconds, what will be his final velocity and how far will he fall?

A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled.

A feather is dropped on the planet other than earth which has very low acceleration due to gravity from a height of 1.40 meters. The acceleration of gravity on the other planet is 1.67 m/s2. Determine the time of feather to fall to the surface of the other planet
