Trajectories of two projectiles are shown in figure.Let `T_(1)` and `T_(2)` be the time periods and `u_(1)` and `u_(2)` their speeds of projection.Then

A

`T_(2) gt T_(1)`

B

`T_(1) = T_(2)`

C

`u_(1) gt u_(2)`

D

`u_(1) lt u_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B, D
Maximum height and time of flight depend on the vertical coponent of intial velocity.
`H_(1)=H_(2) rArr u_(y1)=u_(y2)`, Hence, `T_(1)=T_(2)`
Range `R==(2u_(x)u_(y))/g`
`R_(2) gt R_(1) :. u_(x2) gt u_(x1)` or `u_(2) gt u_(1)`

A projectile has the same range R for angles of projections. If T_(1) and T_(2) be the times of fight in the two cases, then ( using theta as the angle of projection corresponding to T_(1) )

A mass m is suspended separately by two different springs of spring constant k_(1) and k_(2) given the time period t_(1) and t_(2) respectively. If the same mass m is shown in the figure then time period t is given by the relation

consider a head on collision between two particles of masses m_1 and m_2 . The initial speeds of the particles are u_1 and u_2 in the same directioin. The collision starts at t=0 and the particles interact for a time inteval /_\t. Lduring the collision the speed o the first particle varies as v(t)=u_1+t//_\(v_1-u_1) Find the speed of the second particle as as function of time during the collision.
