Question

A particle is projected with 50 m/s at an angle of 37°
with horizontal. If minimum speed of particle during
the motion is vo m/s and time at which speed is
Vo
minimum is to sec then find the value of
?
to +2

Answer 1

Explanation:

Only gravity will have effect to bring the particle down and North acceleration is just going to distort the direction of Range towards North. Therefore, we can apply the standard formula

T=

g

2usinθ

=

10

2×50×sin37

o

=6s
