Question

A ball is throwing at the angle of 37degree at the velocity of 5m/sec show the initial and final velocity in the from of vector

Answer 1

Explanation:

initial vel= 5cos37 i + 5sin37 j

=4 i + 3j

time of flight= 2ucosθ/g=8/10 (g=10m/s²)

final velocity along Y axis be V

V=3 +(-10)(8/10) {first eq of motion}

V=-5m/s

horizontal velocity will be constant

Final vel= 4 i - 5 j
