Embibe Experts Solutions for Chapter: Kinematics, Exercise 1: KCET (UG) 2019

A particle shows the distance-time curve as shown in the figure. The maximum instantaneous velocity of the particle is around the point.

For a body moving along a straight line, the following $v-t$ graph is obtained.

According to the graph, the displacement during

A particle starts from rest. Its acceleration $a$ versus time $t$ is shown in the figure. The maximum speed of the particle will be:

A particle starts from the origin at $t=0 \mathrm{s}$ with a velocity of $10\hat{\mathrm{j}} \mathrm{m} {\mathrm{s}}^{-1}$ and move in the $x-y$ plane with a constant acceleration of $(8\hat{\mathrm{i}}+2\hat{\mathrm{j}}) \mathrm{m} {\mathrm{s}}^{-2}$. At an instant when the $x-$coordinate of the particle is $16 \mathrm{m}, y$-coordinate of the particle is:

The maximum range of a gun on horizontal plane is $16 \mathrm{km}$. If $\mathrm{g}=10{ \mathrm{m} \mathrm{s}}^{-2}$, then muzzle velocity of a shell is

The trajectory of projectile is

For a projectile motion, the angle between the velocity and acceleration is minimum and acute at

Rain is falling vertically with a speed of $12 \mathrm{m} {\mathrm{s}}^{-1}$. A woman rides a bicycle with a speed of $12 \mathrm{m} {\mathrm{s}}^{-1}$ in east to west direction. What is the direction in which she should hold her umbrella?
